What is the impulse that a car with a mass of 6kg experiences when its velocity changes from 23m/s to 6m/s? what is the impulse that the wall creates when it applies a force of 29n over a period of 7s in a collision? a ball of clay with a mass of .1 kg hits the floor and comes to a stop. just before it hits the floor the velocity was -5.69m/s. if the collision took .64 s, how much force is the floor exert on the ball of clay?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
