The pole vaulter successfully clears the bar. They reach a maximum height of 5 m. Calculate their gravitational potential energy at this point.gravitational potential energy, Ep = mgh1470 J2940 J9000 J17,640 J

Calculate the kinetic energy of the pole vaulter when they reach their top speed.kinetic energy, Ek = ½mv2

pole vaulter swings up to launch over the bar. The force from the pole pulls his body upward.What is the direction of this force?

A pole-vaulter of mass 60.5 kg vaults to a height of 5.8 m before dropping to thick padding placed below to cushion her fall.(a) Find the speed with which she lands.

A weightlifter lifts a 8080kgkg barbell off the floor and raises it to a final height of 2.12.1mm. Calculate how much gravitational potential energy the barbell had at the top of the lift. Use g=9.8g=9.8Nkg−1Nkg −1 and include units in your final answer. Round to 00 decimal places. ΔEp=m×g×ΔhΔE p​ =m×g×Δh

After successfully clearing the bar during the pole vault, the vaulter falls to the landing cushion while trying in calculate the impulse / if the mass is 78.4 kg and has a velocity of -12.5. just prior to landing. What in the linear momentum of the vaulter just prior to impact?
