Question

an automobile vehicle has a mass of 1500kg.what must be the force between vehicle and road if the vehicle is to stopped with a negative acceleration of 1.7m/s²?
​

Answer 1

Answer:

mass=1500 kg       acceleration=-1.7m/s²

force = mass*acceleration

f=1500*-1.7

f=1500*-17/10

=150*-17

=-2550 N

Hence the force between the road and the vehicle must be -2550N in order to stop the car.

pls mark as brainliest answer.

Answer 2

Answer:

The force between vehicle and road is -2550N.

Step-by-step explanation:

Given:

• Mass of the automobile vehicle = 15,000kg.
• Acceleration that is needed to stop the vehicle = 1.7m/s²

Need to find:

• The force between vehicle and road.

Explanation:

As it given that,

Mass = 15,000kg

Acceleration = -1.7m/s²

From Newton's second law of motion,

We have:

Force (P) = mass×accerlation

=> 15,000 × (-1.7)

=> -2550 N

Hence,The force between vehicle and road is -2550N.
