Solve the all given parts of following problem:
Problem: A frictionless incline is 5.00 m long (the distance from the top of the incline to the bottom, measured along the incline). The vertical distance from the top of the incline to the bottom is 2.64 m. A small block is released from rest at the top of the incline and slides down the incline.
Part A: How long does it take the block to reach the ground?
Part B: What is the speed of the block just before it strikes the ground?
I need help to find the speed of the block just before it strikes the ground.
