Using a force of 200N, a hockey player does 500 J of work horizontally onto a puck that started from rest on frictionless ice. How far did the puck
travel?

The displacement is 2.5 meters

Explanation:

The formula for work is: W = Fs, where "W" is work, "F" is force, and "s" is displacement.

Since displacement is the shortest distance from start to finish, and the puck travels in a straight line, in this case, displacement = distance traveled.

Let's apply the formula:

The displacement is 2.5 meters

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
