Find the change in the impulse of a vehicle weighing 1.5 tons if it has increased the speed from 18 km / h to 54 km / h.

To find the change in momentum, we subtract the initial momentum from the final momentum, and the formula will write it as
p = mV-mVo
We just have to substitute the values, but firstly we will convert 1.5 tons to kilograms, 18 and 54 km / h to m / s, 1500 kg, 5 m / s and 15 m / s
Now you can substitute values
p = 1500 * 15-1500 * 5 = 15000 (kg * m / s)
Answer; p = 15,000 (kg * m / s)
