a car moving at speed of 5 m/s ,accelerates at a constant rate of 2.50 m/s^2 for 5.00s . what is the car final speed
To find the final speed of the car, we can use the formula for calculating final velocity when there is a constant acceleration:
Final Velocity = Initial Velocity + (Acceleration × Time)
Given:
Initial Velocity (u) = 5 m/s
Acceleration (a) = 2.50 m/s²
Time (t) = 5.00 s
Plug in these values into the formula and solve:
Final Velocity = 5 m/s + (2.50 m/s² × 5.00 s)
Final Velocity = 5 m/s + (12.50 m/s)
Final Velocity = 17.50 m/s
Therefore, the car's final speed is 17.5 m/s.
vf=vi+at=5m/s + 2.50m/s^2 *5s=
=5+12.5=17.5m/s
