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 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 |
