If a car is accelerating downhill under a net force of 3674 N, what additional force would cause the car to have a constant velocity?
Answers
Answer:
Only forces cause acceleration. As such, if an object is accelerating it must be because a non-zero net force is acting onit.It must be changing direction. Acceleration is a vector and vectors have both magnitude and direction. Thus if an object is accelerating it must be changingdirection.It must be speeding up.
If a car is accelerating downhill under a net force of 3674 N, what additional force would cause the car to have a constant velocity?
Given data
The net force of car is,
F n e t = 3674 N .
The total net force acting on the car along the horizontal direction is given as
F g + F n e t = m a
When the car moves with constant velocity, then its acceleration must be zero.
Substitute the value in above expression
F g + F n e t = m × 0
F g = − F n et
F g = − 3674 N
Thus, the amount of force required for the car to move with constant velocity is
− 3674 N .
