been 8m.

This question uses formula for work done

Force given is 100N and the angle is 60°. The distance been 8 m.

W = (F cos 60)S

= (100 cos 60) 8

= 100 x ½ x 8 = 400 J

Therefore here the work done by the force at 60 degree to throw a ball 8 m far is 400 J.

Also find work done if the box is moved 5 m.

This question uses formula for force

Force = F = µN = µmg

Let us put the values F = 0.3 x 10 x 9.8 = 29.4 N

Therefore work done can be found be W = FS

29.4 x 5 = 147 J

Answer: The Force is 29.4 N and Work is 147 J.
