A 50 kg surfer is riding a 25 kg surfboard at a speed of 6.00 m/s and then jumps off the front, moving forward. The surfers velocity when jumping off the surfboard is 2.50 m/s. Find the surfboards velocity immediately after the surfer jumps off.

newton's first law of motion

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.
