Question: (1)..The body of mass 100kg moving with acceleration 5m/s^2 then find the force? I need correct explanation of this question of physics plzz..... don't give any irrelevant answers otherwise i will block them who give here any irrelevant answe F = 80 kg m/s 2. F = 80 N. In the metric system example above, you can see that 80 kg m/s 2 becomes 80 Newtons (N). The reason for that is because the metric system is all nice and tidy, with the actual definition of a Newton being the amount of force required to accelerate 1 kg at 1 m/s 2. Therefore, 1 kg m/s 2 = 1 N, and so, from our. What is the force required to accelerate an object with a mass of 20 kg from stationary to 3 m/s 2? F = m * a. F = 20 kg * 3 m/s 2. F = 60 N.

If this stone hits the ground after 18 seconds and its acceleration due to gravity is g = 9.80 m.s-2. vi = 0 m.s-1. vf = ? a = g = 9.80 m.s-2. t = 18
• Radius of circular motion is 1.5 m (R=1.5m). The acceleration of the ball is a=-22.5i╦å+20.2j╦å m/s┬▓ at 36.9┬░ away from the vertical axis (y-axis). What the problem need: Sketch the vector diagram showing the components of the acceleration. Find the magnitude of radial acceleration. Find the speed and velocity of the ball
• 10. A body moving with uniform acceleration has velocities 20ms-1 and 30ms-1 when passing two points A and B. Then the velocity mid-way between A and B is a. 24m/s b. 24.5 m/s c. 25.5m/s d. 25m/
• ŌĆó Of the units for the four primary dimensions (force, mass, length, and time), three may be chosen arbitrarily. The fourth must be compatible with Newton's 2nd Law. International System of Units (SI Units): base units are the units of length (m), mass (kg), and time (second). The unit of force is derived
• A 40 kg slab rests on a frictionless floor as shown in the figure. A 10 kg block rests on the top of the slab. The static coefficient of friction between the block and slab is 0.60 while the kinetic friction is 0.40. The 10 kg block is acted upon by a horizontal force 100 N. If $g=9.8\,m/{{s}^{2}},$the resulting acceleration of the slab will b
• Now we deal with the case where the mass of an object is changing. We analyze the motion of a rocket, which changes its velocity (and hence its momentum) by ejecting burned fuel gases, thus causing it to accelerate in the opposite direction of the velocity of the ejected fuel (see ).Specifically: A fully fueled rocket ship in deep space has a total mass ${m}_{0}$ (this mass.

Write the relation between S. I. unit and C.G.S. unit of force. Answer: One Newton: If a body of mass 1 kg moves with an acceleration of 1 m/s 2 then force acting on the body is said to be one Newton. 1N = 10 5 Dyne. Relation between S. I. and CGS unit of force is 1 Newton = 1 kg ├Ś 1 ms-2 = 2.69 = 2.7 m/s 2 (b) In this case, the 4 kg block will move at a higher acceleration because the coefficient of friction is less than that of the 2 kg block. Therefore, the two blocks will move separately. By drawing the free body diagram of 2 kg mass, it can be shown that a = 2.4 m/s┬▓. Question-19 :

147.15 N 98.1 N 254.87 N None of these a 1126 The pendulum bob has a mass 10 kg and is released from rest when ╬Ė = 0 with horizontal. If the length of cord is 1 m, determine the velocity of the bob at ╬Ė = 30 degree. 9.81 m/s 3.13 m/s 3.84 m/s None of these b 1127 It is observed that the passengers on the amusement park ride moving with constant speed and the supporting cable are directed at. Since, thrust = force = mass x acceleration F = 2 x 10 4 x 14.8 = 2.96 x 10 5 N. Question 5. 10. A body of mass 0.40 kg moving initially with a constant speed of 10 ms-1 to the north is subject to a constant force of 8.0 N directed towards the south for 30 s. Take the instant the force is applied to be t = 0, the position of the body at that. Sand is gradually added to the bucket until the system just begins to move. a) Calculate the mass of the sand added to the bucket 11.3 kg b) Calculate the acceleration of the system. 0.88 m/s 2 5-14 A sports car of mass 950 kg including the driver caosses the rounded top of a hill (radius 95 m) at 22 m/s Acceleration = resultant force ├Ę mass . 2. Resultant force and calculating acceleration. To calculate the acceleration, you must find the resultant force so that you can divide it with the car's.

Consider a typical simulation with a car of mass 1000 kg moving with a speed 5m/s on a smooth road and colliding with a horizontally mounted spring of spring constant {eq}-6.25x10^{3} {/eq}
