1.Circular Motion: Your evil cousin Throckmorton has come to visit for the weekend. His favourite pastime is skateboarding. You observe him skateboard from rest down a curved, frictionless ramp. If we treat Throckmorton and his skateboard as a particle, he moves through a quarter circle with radius 3.00m. Throcky and his skateboard have a mass 25.0kg. (a) Find his speed at the bottom of the ramp.(b) Find the normal force that acts on him at the bottom of the curve.

- A skier weighing 0.85 kN goes over a frictionless circular hill as shown. If the skier's speed at point A is 8.8 m/s, what is his speed at the top of the hill (point B)?QUESTION 8 OK, same sort of track, but now with d = 2.10 m. Now suppose the blocks starts on the track at x = 4.76 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? A 8.30 m/s B 14.55 m/s C 10.29 m/s D 17.39 m/s10. A stationary block is released on a frictionless ramp at a height of 3.0 m. There are other hill heights along the ramp as shown in the figure. The hills have identical circular tops, and the block does not fly off any hill. If the mass of the block is 4 Kg, what would be the velocity as it passes hill (1)?
