Use the following formula and solve for Vf
Vf=Vi+at
Where
Vf=?
Vi=60m/s
a=-10m/s^2
t=12s
**Since the acceleration is in the opposite direction of the velocity, acceleration is negative.
Vf=60m/s+[(-10m/s^2)(12s)]
Vf=-60m/s
Velocity is in the opposite direction, then velocity initial, so -60m/s is 60m/s north
B is the best answer choice.
a car moving with an initial velocity of 60 m/s south has a constant acceleration of 10 m/s^2 north. After 12 seconds its velocity will be:
A) 60 m/s south B)60 m/s north C) 40 m/s north D) 40 m/s south
