Ou pull your little sister across a flat snowy field on a sled. Your sister plus the sled have a mass of 34 kg. The rope is at an angle of 33 degrees to the ground. As you pull with a force of 26 N, the sled travels a distance of 47 m. How much work do you do?

Work done is 1026.48 J.

Explanation:

Given :

Mass of both sister and sled , m = 34 kg.

Angle from ground of force, .

Force applied , F = 26 N.

Distance travelled , d = 47 m.

We know, work done is, W = F.d =   ( is angle between F and d )=

Here ,

Putting value of , force and distance in work done equation we get,

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.
