You have a velocity function of v(t) = 8t. The starting position of the object described by this function is
zero. Which equations also describe the motion of
this object? *

r(t) = (4t^2) + 2
=
a(t) = 4t^2
r(t) = 4t^2
a(t) = 8
v(t) = 8

A75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high-efficiency motor that has an efficiency of 95.4 percent. the motor operates 4368 hours a year at a load factor of 0.75. taking the cost of electricity to be $0.12/kwh, determine the amount of energy and money saved as a result of installing the high-efficiency motor instead of the standard motor. also, determine the simple payback period if the pu
