A force is applied to stop a moving shopping cart. Explain how increasing the time of impact would change the force required to stop the cart.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

conduct current i mean it makes sense

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
