An elevator has mass 600 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 20.0 m (five floors) in 16.0 s, and it is driven by a motor that can provide up to 40 hp to the elevator. What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg. Please note that 11, 17, and 27 are not correct according to my teacher.

The speed of a block moving on a horizontal frictional surface changes from vi = 15 m/s to vf = 12.5 m/s in a distance of d = 9.5 m. How long in seconds did it take for the block to slow by this amount, assuming the acceleration is constant? If the block has a mass of 1 kg, What is the power supplied to the block by friction? What is the coefficient of kinetic friction between the block and surface μk?
Indicate (with a T of F) whether the statement is true or false. If false, change the underlined word or phrase to make the statement true. A bicycle moving at 5.0 m/s at sea level has more potential energy than a motionless bicycle at the top of a mountain. Mechanical work is calculated by multiplying the magnitude of a force times the amount of time it is applied. The SI unit for work is the joule. One joule is equivalent to 1N: m in SI units 5 tv MacBook Pro

A 108 kg crate slides down a ramp, starting from rest. The ramp is inclined at an angle of 36.4 degrees with respect to the horizontal and has a height of 1.03 m. The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s².
A tower crane has a hoist motor rated at 169 hp. If the crane is limited to using 65.0% of its maximum hoisting power for safety reasons, what is the shortest time in which the crane can lift a 5.50 x 10 kg load over a distance of 89.0 m? Assume the load is lifted at a constant velocity. t = S 仙登

Suppose a stretched spring is used to supply power to a light bulb. The spring has a spring constant k=34.0 N/m and is stretched from its equilibrium length (which is the length where the spring force is zero) by a length 2.24 m. If the spring returns to its equilibrium length in 55.3 seconds, what is the average power in Watts that could be transferred from the spring to the light bulb?
