Answer:
A car was running at 10 km/hr along a straight path. It then increased its speed to 60 km hr in 5 seconds. Solve for its acceleration.
Questions:
A. What was the initial velocity of the car?
B. What was its final velocity?
C. How long did it take for the
car to reach final velocity?
D. What was the acceleration of the car?
Given data:
A. The initial velocity (Vi) of the car: 10 km/hr ( 2.78 m/s )
B. The final velocity (Vf) of the car : 60 km/hr ( 16.67 m/s )
C. The time it took for the car to reach its final velocity: 5 seconds
Required: The acceleration of the car: ? unknown
Formula
We can use the formula ( a = Vf - Vi / t )
Solution
a = Vf - Vi / t
= 16.67 m/s - 2.78 m/s / 5 s
= 13.89 m/s / 5
= 2.78 m/s²
Answer:
The acceleration is 2.78 m/s²
