Question

A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s^2 for 1m. What is the final velocity?

A. 7.0 m/s
B. 5.0 m/s
C. 6.0 m/s
D. 9.0 m/s

Answer 1

The final velocity of the toy car is 7.0 m/s.

Step-by-step explanation:

The final velocity of the toy car can be calculated using the equation vf = vi + at, where vf is the final velocity, vi is the initial velocity, a is the acceleration, and t is the time. In this case, vi = 5.0 m/s, a = 2.0 m/s², and t = 1.0 s.

Substituting the values into the equation, we have vf = 5.0 m/s + 2.0 m/s² * 1.0 s = 5.0 m/s + 2.0 m/s = 7.0 m/s.

Therefore, the final velocity of the toy car is 7.0 m/s, which corresponds to option A.
