A boat has a speed of 2 m/s. It accelerates for half a minute to reach a speed of 8 m/s. Work out the acceleration of the boat.

The acceleration of the boat with an initial velocity of 2m/s and final velocity of 8m/s is 0.2m/s².

HOW TO CALCULATE ACCELERATION:

Where;

8 = 2 + (a × 30)

8 = 2 + 30a

6 = 30a

a = 6 ÷ 30

a = 0.2m/s²

Explanation:

Acceleration is given by dividing change in speed by time taken. The change in velocity is given by subtracting the initial speed from the final speed. In this case, the initial speed is given as 2 m/s while final speed is 8m/s hence the change in speed will be 8 m/s-2 m/s= 6 m/s

Time is half a minute which is equivalent to 0.5*60=30 seconds

Therefore, acceleration will be 6/30=0.2 m/s2
