calculate the force required to produce an acceleration of 2ms in a body mass of 10kg
Here,
Mass, m = 10 kg
Acceleration, a = 2 m/s2
We know, Force, F = ma = (10)(2) = 20 N
(a) State Newton’s third law of motion and give two examples to illustrate the law. (b)Calculate the force required to produce : (i) an acceleration of 2.5 m/s2 in a body of 4 kg (ii) an acceleration of 3.0 m/s2 in a body of 10 kg.
If mass and radius of earth is 6.0∗1024 kg and 6.4∗106 m respectively, calculate the force exerted by earth on a body of mass 1 kg. Also, calculate : (i) acceleration produced in the body of mass 1 kg, and (ii) acceleration produced in the earth
