Question

pleasesmone see if u can answer these.

1. A constant force of 23 Newtons ( N ) acts on a hocky ball to move it 15 metres ( M ) from inside the goal shooting zone to the back of the goal. How much work was done on the hocky ball

2. How much work is done by Mr Buckland face trying to pushstart his g*y *** car, if he has to push it 30 freaken M? Once he gets the car moving, The force he uses stays constant. it takes 383 N of force to move the car.

3. If a skateboard moved 278 center metres ( CM ) wen pushed by a constant force of 18.32 N, how much work was done on the freaken skatebord...??

first to answer these right wns a 1 way first class ticket to... a....a.....a....aaAAALBAQUERQUE.. ok no u get 10 points isnt that god enough..?

Answer 1

(i) Work done = Force x Displacement = 23 Newtons x 15 m = 545 N-m

(ii) Again the same principle...

Work = 383 x 30 = 11490 N-m

(iii) Work = 2.78 m x 18.32 N = 50.9296 N-m
