A 60-kg cheetah reaches a speed of 30 m/s as it chases its prey. What is the kinetic energy of the cheetah? A. 900J

B. 1,800

C. 27,000

D. 54,000 J

answer; how far out of place which the object finished relative to the starting location;

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.
