A motorboat traveling on a straight course slows uniformly from 65 km/h to 35 km/h in a distance
of 45 m.
Part A
What is the magnitude of the boat's acceleration?

2.572 m/s²

Explanation:

Convert the given initial velocity and final velocity rates to m/s:

The motorboat's displacement is 45 m during this time.

We are trying to find the acceleration of the boat.

We have the variables v₀, v, a, and Δx. Find the constant acceleration equation that contains all four of these variables.

Substitute the known values into the equation.

The magnitude of the boat's acceleration is |-2.572| = 2.572 m/s².

the answer is 12 as i may remember
