Question

(b) the missile is flying off at a velocity or 4. A vehicle having a mass of 1,500 kg was moving with an acceleration of 1.7 m/s2. After moving for 600 m it stopped accelerating. (a) How much force should the brakes apply to bring it to a standstill? (b) How much distance will it cover while decelerating? o time table of an nhiect in motion:​

Answer 1

Correct option is

B

-2550 N

Mass of vehicle = 1500kg

Retardation required = −1.7ms−2

Force between road and vehicle = 1500×−1.7=-2550 N

This is a friction force.
