Use the formula for kinetic energy.
KE=1/2mv^2
KE=1/2*(82kg)*(2.8m/s)^2
KE=321.4 J
The answer is C

As the plane falls the parabolic path remains directly below as the plane continues to fly over. This give more of an overview. When the package falls vertical acceleration happens as there is a vertical velocity as the package falls form high above. The downwards motion of gravity acts on the package if the approximated projectile motion ignoring air resistance.

In each cycle, a heat engine an input of 1940 J of heat and exhausts 1480 J of heat. What is the thermal efficiency?
AleksAgata [21]

Answer:

0.237 (23.7 %)

Explanation:

The thermal efficiency of an engine is given by:

\eta=\frac{W}{Q_{in}}

where

W is the useful work output of the engine

Q_{in} is the heat in input

Here we have:

Q_{in}=1940 J

and the work done is the total heat in input minus the heat exhausted:

W=1940 J - 1480 J=460 J

So, the efficiency is

\eta=\frac{460 J}{1940 J}=0.237 (23.7 %)
