What is the acceleration of a boat if it starts from rest and then reaches a velocity of 24m/s in 6.0seconds

1 answer

To find the acceleration of the boat, we can use the formula for acceleration:

\[ a = \frac{\Delta v}{\Delta t} \]

where:

  • \( a \) is the acceleration,
  • \( \Delta v \) is the change in velocity,
  • \( \Delta t \) is the change in time.

In this case:

  • The initial velocity \( v_0 = 0 \) m/s (the boat starts from rest),
  • The final velocity \( v = 24 \) m/s,
  • The time interval \( \Delta t = 6.0 \) seconds.

We can find the change in velocity \( \Delta v \):

\[ \Delta v = v - v_0 = 24 , \text{m/s} - 0 , \text{m/s} = 24 , \text{m/s} \]

Now, we can substitute these values into the acceleration formula:

\[ a = \frac{24 , \text{m/s}}{6.0 , \text{s}} = 4 , \text{m/s}^2 \]

So the acceleration of the boat is \( 4 , \text{m/s}^2 \).
