Hello , i need some help solving a few questions. please help :) thankyou a)A pool Cue exerted an average force of 160N on a cue ball over a distance of 0.012m How much work did the cue do on the ball. b)If all the work done on (a) was transformed into kinetic energy of 0.0200kg cue ball, what was the speed of the ball? c) Light from the sun reaches the earth in 8.3min. The speed of light is 3.00x10g m/s. in kilometer, how far is the earth from the sun? d)An electron travels at a unifor velocity of 3.2x10g m/s, how much time is required for a displacement of 1.0m? e)A person walks 5.0 km torwards the east in 2.0 hours,then 1.5 km towards the west in 0.5 hour, and finally 10.0 km torwards the east again in 2.25 hour.
