Asled is pulled along a level path through snow by a rope. a 20-lb force acting at an angle of 40° above the horizontal moves the sled 90 ft. find the work done by the force. (round your answer to the nearest whole number.)

Work one by the force, W = 1378.87 lb-ft

Explanation:

It is given that,

Force acting on the sled, F = 20 lb

Angle between the force and the horizontal, θ = 40°

Distance moved, d = 90 ft

We need to find the work done by the force. We know that the work done can be calculated as :

W = 1378.87 lb-ft

So, the work done by the force is 1378.87 lb-ft. Hence, this is the required solution.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
