Question

An automobile vehicle has a mass of 1500 kg. What must be the force
between the vehicle and road, if the vehicle is to be stopped with the
negative acceleration of 1.7 m/s to the power of 2 .
With steps Pls
.

Answer 1

Solution:

Using Newton’s second law of motion

Formula:

Force = Mass x Acceleration

Substituting the known values we get

F= 1500 x (-1.7) = -2550 N

Answer:

Hence, the force between the automobile and the road is -2550 N, in the opposite direction of the automobile’s motion.

Answer 2

Given

• Mass of the automobile vehicle, m = 1500 kg
• Final velocity, v = 0 (finally the automobile stops)
• Acceleration of the automobile, a = 1.7 ms2

Find out

• We need to find the force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of -1.7 ms2

Solution

$\hookrightarrow$ Using Newton’s second law of motion

Formula

$\mapsto$ Force = Mass × Acceleration

Substituting the known values we get

$\mapsto$ F = 1500 × (-1.7) = -2550 N

$\large\red\bigstar$ Hence, the force between the automobile and the road is -2550 N, in the opposite direction of the automobile’s motion.
