a block of mass 2.4 kg is sitting on a frictionless ramp with aspring at the bottom that has a spring constant of 490N/m the angleof the ramp with respect to the horizontal is 31 degrees
A.) the block starting from rest slides down the ramp a distance78 cm before hitting the spring how far in cm is the springcompressed as the block comes to momentary rest?
B.) After the block comes to rest the spring pushes the blockback up the ramp how fast in meters per second is the block movingright after it comes off the spring
C.) what is the change of the gravitational potential energy injoules between the original position of the block at the top of theramp and the position of the block when spring is fullycompressed?
