Evaluate (n-m)^2 for m =-3 and n= 7

100

Step-by-step explanation:

(7-(-3))^2 = 10^2 = 100

This problem is on the circular motion.

Assuming a basis of 1 sec, there would be 6 revolutions, which is equivalent to 6 circumference of the pulley. One revolution means one circumference, which is 2(pi)(10cm) or 20(pi) cm.

Therefore, linear speed is 6(20)(pi) cm/s or 376.99 cm/s or 3.77 m/s
