A car is driving at a velocity (v) of 15 m/s. If you were calculating the kinetic energy (KE) of the car, you would have to complete which of the following steps? * Multiply 15 m/s by 2
Divide 15 m/s by 0.5
Multiply 15 m/s by 15 m/s
Add 15 m/s to the PE of the car

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.
