Question

05-An automobile vehicle has a mass of 1500 kg.
What must be force between the vehicle and road if
Vehicle is to be stopped with a negative
Acceleration of 1.7m/s2?​

Answer 1

Answer:

2550 N

Explanation:

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 road if the vehicle is to be stopped with a negative acceleration of 1.7 ms2

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

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

Answer 2

Answer:

Force applied,F=ma

m,mass the vehicle=1500kg

a, negative accerlation= -1.7ms^-2

Force between vehicle and road F=?

F,force=1500×1.7N

= -2500N

Force=2550N
