To calculate the acceleration of the dump truck, you can use the equation:
a = (v - u) / t
Where:
- a is the acceleration
- v is the final velocity (25 m/s)
- u is the initial velocity (15 m/s)
- t is the time taken (4 seconds)
Substituting the given values into the equation:
a = (25 m/s - 15 m/s) / 4 s a = 10 m/s / 4 s a = 2.5 m/s²
Therefore, the acceleration of the dump truck is 2.5 m/s².
