Answer:
Total work done is 2606.08 J.
Explanation:
Given :
Mass of box , m = 23 kg .
Force applied , F = 100 N .
Angle from horizon , .
Coefficient of kinetic friction , .
Distance travelled by box , d = 34 m .
Now ,
Total work done = work done by boy + work done by friction.
Hence , this is the required solution.
Answer:
A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.
Explanation:
An object moving at a constant velocity, is changing its displacement at an equal time.That is, the object is moving on a straight line at a constant speed.
Also an object with a constant velocity is not accelerating, since acceleration is the change in velocity with respect to time.
Therefore, A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.

Answer:
340cm = 3.4m
Explanation:
When converting units: cm to m, then you need to divide the cm by 100 to get its unit in m.
