Question

How do you determine the initial velocity of a charies toy car if it is already accelerated with 13.3m/s over a period of 3 seconds with an acceleration of 3.2 m/s²?

Answer 1

To determine the initial velocity of the toy car, we can use the following kinematic equation:

v = u + at

Where: v is the final velocity, u is the initial velocity, a is the acceleration, t is the time taken.

Given: Final velocity (v) = 13.3 m/s Acceleration (a) = 3.2 m/s² Time (t) = 3 seconds

Substituting the values into the equation:

13.3 m/s = u + (3.2 m/s²)(3 s)

Now, solve for the initial velocity (u):

13.3 m/s - (3.2 m/s²)(3 s) = u

13.3 m/s - 9.6 m/s = u

3.7 m/s = u

Therefore, the initial velocity of the toy car is 3.7 m/s.
