To find the initial velocity of the toy car, we can use the equation:
a = (Vf - Vi)/t
where:
a = acceleration of the car = 1.8 m/s^2
Vf = final velocity of the car = 12.2 m/s
t = time = 3 seconds
Rearranging the equation to solve for Vi, we have:
Vi = (Vf - a*t)
Substituting the given values:
Vi = (12.2 m/s - 1.8 m/s^2 * 3 s)
Vi = (12.2 m/s - 5.4 m/s)
Vi = 6.8 m/s
Therefore, the toy car's initial velocity is 6.8 m/s.
a toy race car zooms across ground with an acceleration of 1.8m/s^2. after 3 seconds it has a final velocity of 12.2 m/s, what is the toy cars initial velocity
a=(Vf-Vi)/t
22.8 m/s
6.8 m/s
9.8 m/s
1.8 m/s
