Question

A body of mass 2Kg is at rest at the origin of a frame of reference. A force of 5 N acts on it att= 0. The force acts for 4 seconds and then stops. Q49. What is the acceleration produced by the force on the body? a) 2 m/s*b) 2.5 m/s*c) 3 m/s*d) 3.5 m/s Q50. What is the velocity at t= 4s? a) 20 m/sb) 5 m/sc) 15 m/sd) 10 m/s_ Q51. For the periodt=2s, t = 4s &t= 6s, the velocities v are: a) 5, 15, 25b) 10, 20,30c) 5, 10, 15 d) 8, 16, 24_ Q52. Find the distance travelled in 6s. a) 45 mb) 35 mc) 42 m d) 36 m
