Bill forgets to put his car in park and it starts rolling west. when it is moving at a speed of 3.5 m/s, it collides with tanya's car, which is moving at a speed of 2m/s east. bill's car bounces backward (to the east) at a speed of 2 m/s. bill's car has a mass of 900 kg, and tanya's car has a mass of 1100 kg.

a. what is the total momentum of the system before collision?

b. what is the total momentum of the system after the collision?

c, what is the velocity of tanya's car after the collision?

Asoccer ball of mass 0.43 kg is rolling with velocity < 0, 0, 1.8> m/s, when you kick it. your kick delivers an impulse of magnitude 2.7 nâ·s in the direction. the net force on the rolling ball, due to the air and the grass, is 0.22 n in the direction opposite to the direction of the ball's momentum. using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked. use the approximation . (express your answer in vector form.) < entry field with incorrect answer 12.97 , entry field with correct answer 00 , entry field with incorrect answer 2.7 > m
