What is the force which makes a 2000 kg vehicle accelerate by 3.2 meters per second squared?

Answer;

Force = 6400 Newtons

Solution;

From the Newton's second Law of motion, the resultant force is directly proportional to the rate of change in linear momentum.

Therefore;

F = (mv-mu)/t; But since (v-u)/t = a

Then; F= ma, where F is the force , m is the mass and a is the acceleration.

Force = 2000 × 3.2

= 6400 N

the answer is b ) square root of 5
