A 0.05-kg toy car is initially moving at 1.4 m/s. Since the battery is losing power, the toy car has slowed down to 0.7 m/s. Calculate the impulse of the toy car. Input the numerical value only; do not include the units.

A 1-oz bullet is traveling with a velocity of 1400 ft/s when it impacts and becomes embedded in a 5-lb wooden block. The block can move vertically without friction. Determine (a) the velocity of the bullet and block immediately after the impact, (b) the horizontal and vertical components of the impulse exerted by the block on the bullet.

I don't understand this hw problem.

A 0.12-kg ball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. What is the magnitude of the linear impulse experienced by the ball?

A 0.150 kg lump of clay is dropped from a height of 1.75 monto the floor. It sticks to the floor and does not bounce.   What is the magnitude of the impulse ? imparted to the clay by the floor during the impact? Assume that the acceleration due to gravity is ?=9.81 m/s2.   The force exerted by the floor on the clay is plotted as a function of time in the figure. What must have been the maximum force ?max exerted by the floor on the clay?

A hockey player passes a 0.168kg puck that is initially sliding backward at 5.00m/s.
