John is building a frictionless track with a block (? = 20.0kg) sliding on it (no flying up). The block is initially at rest at point A, and it is pulled by an external force ? = 60.0N (with an angle ? = 25.0 ° from the surface of the track) over a distance ? = 3.50 to point B. There are no external forces on the block after point B and the block continues to slide along the track until the magnitude of its velocity is ?C = 0.700m/s at point C. What is the height ℎ of point C (relative to point A)?

Question
John is building a frictionless track with a block (? = 20.0kg) sliding on it (no flying up). The block is initially
at rest at point A, and it is pulled by an external force ? = 60.0N (with an angle ? = 25.0
°
from the surface of
the track) over a distance ? = 3.50 to point B. There are no external forces on the block after point B and the
block continues to slide along the track until the magnitude of its velocity is ?C = 0.700m/s at point C. What is
the height ℎ of point C (relative to point A)?
