Question

A block of mass m = 3.70 kg is released from rest from point A  and slides on the frictionless track shown in the figure below. (Let ha = 5.40 m.)

 

find the speed at B and C

b) Determine the net work done by the gravitational force on the block as it moves from point A to point C .

The image depicts a roller coaster-like track with three main points labeled A, B, and C. 

- **Point A**: A block with mass \( m \) is located at the highest point of the track. This height is denoted as \( h_a \).

- **Point B**: This is a lower point on the track, at a height of 3.20 meters above the ground.

- **Point C**: This point is further along the track, with a height of 2.00 meters above the ground.

The track is designed as a series of smooth waves, showcasing the potential energy changes as the block moves along the different heights. The image illustrates concepts of energy conservation, kinetic and potential energy in physics, as the block transitions between different elevations on the track.
