a motorcycle traveling at 25m/s accelerates at a rate of 7.0 m/s2 for 6.0 seconds. what is the final speed of the motorcycle?
To find the final speed of the motorcycle, we can use the formula:
final velocity = initial velocity + (acceleration * time)
Given:
Initial velocity (u) = 25 m/s
Acceleration (a) = 7.0 m/s²
Time (t) = 6.0 seconds
Using the formula:
final velocity = 25 m/s + (7.0 m/s² * 6.0s)
final velocity = 25 m/s + 42 m/s
final velocity = 67 m/s
Therefore, the final speed of the motorcycle is 67 m/s.
