Question
A block on a level horizontal surface of negligible friction is initially traveling at 20 m/s to the left. A horizontal force F is exerted to the right on the block for the time interval 0 <t < 0.10 s. The magnitude of the force is given as a function of time t by the equation F = at, where a = 240 N/s and t is in seconds. %3D What is the magnitude of the change in momentum of the block due to the horizontal force? A 1.2 kg • m/s B 12 kg• m/s 24 kg • m/s 240 kg • m/s The change in momentum of the block cannot be determined without knowing the block's mass.
