- A skier, starting from rest, moves from the top of a ramp to the bottom. If the vertical drop is 3.12 meters, what is the speed in m/s of the skateboarder at the bottom of the ramp. (neglect friction). Can you help with a visual aid; and then, explain the mechanics of calculation.Disregarding friction, a roller coaster with a vertical drop of 46 m will achieve a speed of about 30 m/s. If the height of the drop is doubled, how much the speed is going to be?A man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 30.0 m/s and has a speed of 28.4 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance. ורו
- A 565 kg roller coaster is poised at the top of a 102.5 m hill. How fast will the roller coaster be going when it travels over the next hill, 40.0 m high?A man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 28.0 m/s and has a speed of 25.6 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance.A frictionless roller coaster cart is moving at 3.4 m/s when it is 46 m above the ground. It coasts along the hilly track, at one point reaching the top of hill, 19.4 m above the ground. Find the cart's speed at the top of the hill. v= m/s
- A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 4.16 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.7 m. What will the block s speed be when it reaches x = 0? 8.79 m/s 5.86 m/s 4.14 m/s 2.90 m/sAn object is moving at 3.5 m/s as it rolls up a frictionless hill. How fast will the object be moving when it is 0.5 m above the ground?A single frictionless roller-coaster car of mass m= 200 kg tops the first hill with speed vo = 16.0 m/s at height h = 60.0 m.

- A 565 kg roller coaster is poised at the top of a 102.5 m hill. How fast will the roller coaster be moving at the bottom of the incline (h=0)?A brick has a mass of 1.3kg. It is dropped (from rest) from a height of 18.8m. What is the speed of the brick when it hits the ground? Your Answer:A physics student ties a ball with a mass 0.30kg to a string which can exert a maximum force of 41 N without breaking. The student swings the ball in a circle with a radius of 0.91 m, slowly increasing the speed until the string breaks. The circle is oriented vertically so that the ball moves up and down while traveling in a circle. What is the speed of the ball as the string breaks?
