Question1
The bumper car with mass m1 = 109 kg is moving to the right with a velocity of v1 = 4.9 m/s. the second bumper car with mass m2 = 84 kg is moving to the left with velocity of v2 = -3.6 m/s. The two cars have an elastic collision. Assume surface is frictionless.
Question2
Sam, who’s mass is 61.0kg, takes off down a 53.0m high, 8.00 slopes on his jet-powered skis. The skis have a thrust of 200N. Sam's speed at the bottom is 41.0m/s. What is coefficient of kinetic friction of his skis on snow? Contain motion diagram and free body Diagram.
Question3
A shot putter throws the shot with an initial speed of 15.9m/s at a 36.0 angle to the horizontal. Calculate the horizontal distance travelled by the shot if it leaves the athlete's hand at a height of 2.10m above ground.
