A 52.0 skateboarder wants to just make it to the upper edge, Ask an Expert

Academics

Q1. A 52.0 skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of a circle with a radius of 2.90. What speed does he need at the bottom?

Q2. A uniform electric field of magnitude 334 N/C is directed along the +y-axis. A 6.00 µC charge moves from the origin to the point (x, y) = (-40 cm, -33 cm).

What is the change in the potential energy linked with this charge?
