Question
In a factory it is desired to lift $2000 \mathrm{~kg}$ of metal through a distance of $12 \mathrm{~m}$ in 1 minute. Find the minimum horsepower of the engine to be used.
Step 1
The formula for work done is given by $W = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity, and $h$ is the height. Show more…

A 1300 -kg car is to accelerate from rest to a speed of $30.0 \mathrm{~m} / \mathrm{s}$ in a time of $12.0 \mathrm{~s}$ as it climbs a $15.0^{\circ}$ hill. Assuming uniform acceleration, what minimum power is needed to accelerate the car in this way?
The mass of an elevator and its occupants is $1200 \mathrm{kg}$. The electric motor that lifts the elevator can provide a maximum power of $15 \mathrm{kW}$. What is the maximum constant speed at which this motor can lift the elevator?
In order to keep a leaking ship from sinking, it is necessary to pump $12 \mathrm{~kg}$ of water each second from below deck $2.1 \mathrm{~m}$ upward and over the side. What is the minimum horsepower motor that can be used to save the ship $(1 \mathrm{hp}=746 \mathrm{~W})$ ?
