A person of mass 75kg runs towards a stationary cart (call it cart A) of mass 125 kg at a speed of 8 m/s and jumps in it. The cart is at the top of an incline plane of height 2.0m and angle of inclination 30°. The cart with the person in it rolls down the plane all the way to the bottom of the plane (ignore friction or air resistance) where it collides elastically into an identical empty stationary cart (call it cart B). (A)What is the speed of cart A after the person jumps in? (B)What is the speed of cart A at the bottom of the incline? (C)Write down the equation(s) you need to use to determine the speed of the empty cart B after the collision. (D)If the speed of cart A + person is equal to 1.60 m/s a
A person of mass 75kg runs towards a stationary cart (call it cart A) of mass 125 kg at a speed of 8 m/s and jumps in it. The cart is at the top of an incline plane of height 2.0m and angle of inclination 30°. The cart with the person in it rolls down the plane all the way to the bottom of the plane (ignore friction or air resistance) where it collides elastically into an identical empty stationary cart (call it cart B).
(A)What is the speed of cart A after the person jumps in?
(B)What is the speed of cart A at the bottom of the incline?
(C)Write down the equation(s) you need to use to determine the speed of the empty cart B after the collision.
(D)If the speed of cart A + person is equal to 1.60 m/s after the collision, what is the magnitude of the impulse delivered to cart A + person during the collision?
