MY NOTES PRACTICE ANOTHER A man on a motorcycle plans to make a jump as shown in the figure. h If he leaves the ramp with a speed of 29.5 m/s and has a speed of 27.3 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. 6.0902 X Is energy conserved? Where is a convenient place for zero gravitational potential energy? Can you write expressions for the kinetic energy and the potential energy at both the end of the ramp and the top of the trajectory? m Additional Materials Reading8. [0/3 Points] DETAILS PREVIOUS ANSWERS OSCOLPHYS2016ACC 7.7.P.039. MY NOTES PRACTICE ANOTHER (a) Find the useful power output (in W) of an elevator motor that lifts a 2200 kg load a height of 35.0 m in 12.0 s, if it also increases the speed from rest to 4.00 m/s. Note that the total mass of the counterbalanced system is 10,000 kg-so that only 2200 kg is raised in height, but the full 10,000 kg is accelerated. (Enter a number.) 292000 X W (b) What does it cost (in cents), if electricity is $0.0900 per kW . h? (Enter a number.) 875 * cents
