Two pole-vaulters just clear the bar at the same height. The first lands at a speed...
A 44-kg pole vaulter running at 10 m/s vaults over the bar. Her speed when she is above the bar is 1.4 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar. m
A 69-kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.5 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar. _____m
A 63kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.5 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
A 54 kg pole vaulter intends to pass over a 6.4-meter high bar. She needs to maintain a minimal speed of 0.72 m/s at the top in order to pass the bar. What is the minimum speed at which she should run in order to attain the height? Neglect air resistance, as well as any energy absorbed by the pole Answer in units of m/s and round to one decimal place. Hints: Mechanical energy is conserved during vaulting. KE at...
12. A pole-vaulter approaches the takeoff point at a speed of 9.0 m/s. Assuming that only this speed determines the height to which she can rise, fins the maximum height at which the vaulter can clear the bar.
QUESTION 3 A 54 kg pole vaulter intends to pass over a 6.9-meter high bar. She needs to maintain a minimal speed of 0.79 m/s at the top in order to pass the bar. What is the minimum speed at which she should run in order to attain the height? Neglect air resistance, as well as any energy absorbed by the pole. Answer in units of m/s and round to one decimal place. Hints: Mechanical energy is conserved during vaulting....
a.) A 49-kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.1 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar. b.) A skier of mass 60 kg is pulled up a slope by a motor-driven cable. (a) How much work is required to pull him 80 m up a 30° slope (assumed frictionless) at a...
Chapter 06, Problem 32 A pole-vaulter just dlears the bar at 4.09 m and falls back to the ground. The change in the vaulter's potential energy during the fall s 380 Number Units
Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 36.5 m/s at an angle of 31.0° above the horizontal. (a) Assuming that the a ands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. What constant acceleration equations will allow you to find the range, given the speed and angle? (Note that, depending on your...
The specialty of an athlete on the women's track team is the pole vault. She has a mass of 44 kg and her approach speed is 8.7 m/s. When she is directly above the bar, her speed is 1.7 m/s. Neglecting air resistance and any energy absorbed by the pole, determine the amount she has raised herself as she crosses the bar. m A roller coaster car is pulled up the first (biggest) hill, 103 meters above the subsequent bottom...
