Consider the skateboarder as a simple particle. Express your answer with the appropriate units. Vj = Submit Part B 00 μA Value Request Answer μA Units In reality the skateboarder isn't a simple particle: Assume that his mass in a deep crouch is concentrated 0.75 m from the half- pipe. If he remains in that position all the way up, what initial speed does he need to reach the upper edge? Express your answer with the appropriate units. Vi crouch = Value ? Unitsarrow_forwardYou are designing a ski jump ramp for the olympics. You need to calculate the vertical height (h) from the starting gate to the bottom of the ramp. The skiers push off hard with their ski poles at the start, just above the starting gate, so they typically have a speed of 2.0 m/s as they reach the gate. For safety, the skiers should have a speed of no more that 30.0 m/s when they reach the bottom of the ramp. You determine that for an 85.0 kg skier, friction and air resistance will do a total work magnitude 4000 j on him during his run down the slope. What is the maximum height (h) for which the maximum speed will not be exceeded?arrow_forward

After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is med ocum 15.0 m?
