Question:

An empty truck with mass of 2500kg has an engine that will accelerate at a rate of $\displaystyle 1.5m/s^2 $ .What will be the acceleration when the truvk has an additional load of 1500kg?

Attempt:

2500*1.5=4000*x

$\displaystyle x=\frac{2500*1.5}{4000} =0.9375 $

Am I correct ?

Thank you
