Question

A 7500 kg vehicle starts off from rest and reaches a velocity of 20 (m)/(s )in 5.00 seconds. What is the vehicle's acceleration and how much momentum does it have after it has reached this final velocity?

Answer 1

The vehicle's acceleration is 4 m/s², and its momentum after reaching the velocity of 20 m/s is 150000 kg*m/s.

Step-by-step explanation:

The problem given is a physics question involving concepts of acceleration and momentum. To find the vehicle's acceleration, we use the formula:

a = Δv / Δt

where Δv is the change in velocity and Δt is the change in time. Given the vehicle starts from rest (initial velocity of 0 m/s) and reaches 20 m/s in 5 seconds, the vehicle's acceleration is:

a = (20 m/s - 0 m/s) / 5.00 s = 4 m/s²

For the vehicle's momentum, the formula is:

p = m * v

where m is mass and v is velocity. The vehicle's momentum after reaching the final velocity is:

p = 7500 kg * 20 m/s = 150000 kg*m/s

Therefore, the vehicle's acceleration is 4 m/s² and its momentum is 150000 kg*m/s.
