5.An automobile vehicle has a mass of 1500 kg. What must be the force

1.	5.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 a negative acceleration of 1.7 m s–2?
Answer» 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 Answer Hence, the force between the automobile and the road is 2550 N, in the direction opposite to the motion of the automobile.

5.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 a negative acceleration of 1.7 m s–2?

Answer»

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

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

Answer

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