A 245 g toy car is sitting on top of a frictionless hill, when it is released, it comes into contact with a spring with a k = 62 N/m. The spring is compressed 45 cm. Determine the height of the initial release point. Determine the speed of the car when it compressed the spring 10 cm

2. A block of mass m approaches the foot of a hill with a speed of vo. It heads up the frictionless hill of height h and reaches the top. The top is rough with coefficient of kinetic friction μk over a distance d. After the rough patch, there is a spring of spring constant k. Ignore air resistance. a) Assume that the block does not make it through the rough patch. Determine the length L that it travels through the rough patch before coming to rest. b) For the situation in (a), what is the work done by non-conservative forces? c) Now assume that the block does make it through the rough patch. Determine the maximum compression of the spring.

A spring with k= 360 N/m is compressed x = 11cm by a 1.85 kg block on a horizontal table with coefficient of friction of 0.38. This means there is friction everywhere on the table! A. What is the speed of the block when it is released? B. Determine the distance the block travels before it comes to rest.

A spring with a constant k=100 N/m is placed after point-C in the frictionless ABC path. A ball of mass of 2 kg is initially at rest and released from point A. The ball travels through the ABC path and finally hits the spring. What is the velocity of the ball at point B and C?. What is the maximum compression in he spring? (9.8 m/s^2)
