Question #103152

A small radio controlled car is moving to the right at 14 m/s at t=0s, with a constant acceleration of 2.0 m/s2 [L]. FIND:

The velocity of the car at t=6.0s

How long it takes the car to come to a rest.

At what time is the displacement of the car is equal to 40.0 m [R]

The velocity of the car at t=6.0s

How long it takes the car to come to a rest.

At what time is the displacement of the car is equal to 40.0 m [R]

Expert's answer

The velocity of the car at t=6.0s

Time is

We have

"40=14t-0.5(2)t^2"

"t_1=4\\ s"

"t_2=10\\ s"

The second time will be when car returns backwards.
