You see an advertisement for a new free fall ride at an amusement park. the ad says the ride is 50 meters tall and reaches a speed of 28m/sec at the bottom. how efficient is the ride? hint: you can use any mass you wish because it cancels out.

Explanation :

It is given that the ad says the ride is 50 meters tall and reaches a speed of 28m/sec at the bottom.

The efficiency is defined as the ratio of the output energy and the input energy.

In this case, the output energy is kinetic energy and the input is potential energy.

Output energy,

Input energy,  

Efficiency becomes :

or

The ride is 80% efficient.

the force required to move the cart is divided by three or 33.33 n.

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
