The position of a crate sliding down a ramp is given by x = (0.25 t 3) m and y = (1.5t 2) m, where tis in seconds. Determine the velocity and acceleration when t = 2 sec (magnitudes and angles)

c) up is the direction the magnetic force is acting on the charge.

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.
