Question

the velocity of an object of mass 50 kg increases from 3 metre per second to 12 metre per second what will be the force required for this​

Answer 1

Data insufficient and kindly complete the question.

Answer 2

Given that,

Mass of the object, m = 50 kg

Initial speed of the object, u = 3 m/s

Final velocity of the object, v = 12 m/s

Let time, t = 1 s

To find,

The force required for this.

Solution,

Newton's second law of motion gives the magnitude of force as :

$F=ma\\\\F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{50\times (12-3)}{1}\\\\F=450\ N$

So, the force of 450 N is required for this.
