Part Ia: Exploring the effect of mass on the conservation of energy without friction quantitatively. With the Grid on, start the skater at the highest point in the parabolic half-pipe (y = 6.00 m) above the ground. and let him skate. If the skater + skateboard mass is 60.0 kg and g = 10.0 m/s2. 7. Draw a free body diagram of the skater halfway down left side of the ramp, identify all forces acting on the skater with no friction. Label a coordinate system and draw your force vectors appropriately. How much work is done by the normal force of the ramp on the skater? Explain.
