Momentum-Energy

Q- A car with a mass of mcar = 2080 kg moving towards east and a truck with mass mtruck = 8990 kg moving towards north with velocity vtruck = 8 m/s, enter an intersection. When the two collide they stick together and slide at an angle of 300 north of east.

a) What is the speed of the pair after the collision?

b) What is the eastward component of the momentum of the pair after the collision?

c) At what speed was the car traveling before the collision?

d) What is the kinetic energy of the pair before the collision?

e) What is the kinetic energy of the pair after the collision?
