a potter carries 30 bricks to a distance of 50 m in 25 seconds. If the weight of 1 brick is 12N. Calculate work down and power​

(I)W=18×10³ J

(ii) P=720W

Explanation:

30 Bricks = 1brick weight× 30 Bricks

30 Bricks= 12×30

=360N

Distance=50m

Time= 25s

1. Work done= Force× Distance

=360×50

= 18×10³ J

2. Power= Work done/ Time

18×10³/25

Power= 720W.

0.55x745.7j and a calculator

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
