An automobile vehicle has a mass of 1500 kg. What mustbe the force between the vehicle and road if the vehicle is tobe stopped with a negative acceleration of 1.7 m s?​

Answer»

Answer:

-2250 N

EXPLANATION:

According to the Newton's second law of MOTION

F = m*a

we have given that

mass of the VEHICLE (m) = 1500 kg

NEGATIVE acceleration (a) = -1.7m/s²

Therefore,

F = ( 1500kg ) × (-1.7 m/s²)

F = - 2550 N

here the negative sign indicates that the force is applied apposite to the direction of the motion of the vehicle
