The statements that are true are;
- the magnitude of work done by frictional forces on the crate is 100 J
- the magnitude of work done by the applied force on the crate is 100 J
<h3>What is work done?</h3>
Work is said to be done when te force applied travels a distance in the direction of the force. Now we can see that when the force is applied by shoving the crate, work is done, an additional work is done by friction to bring the crate to a stop.
Hence, the following are true;
- the magnitude of work done by frictional forces on the crate is 100 J
- the magnitude of work done by the applied force on the crate is 100 J

Answer:
Using the pythagoras theorem
S²=9²+4²
S²=81+16
S²=97
S=9.85km.
In finding the direction
tan□=opposite/Adjacent
=4/9
□=23.96
¤=90-23.96
=66.03 degrees
9.85, N 66.03 E
Gravity is affected by mass and distance
