Question

What will be the acceleration of a body of mass 5kg if a force of 200 newton act on it.​

Answer 1

Answer:

Here is your solution:

Q- What will be the acceleration of a body of mass 5kg if a force of 200 newton act on it

Given :-

body of mass 5kg .

force of 200 newton

To find the acceleration of a body :-

We know that

according to

Newton's second law of motion.

relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law i.e

F = ma

where

force (F) acting on an object .

mass (m) of an object.

acceleration (a)

f=ma

200n = 5kg ×a

a= 200n/5kg

a=40n/kg.

hence

acceleration of a body is 40n/kg

Answer 2

Answer:

Yes, even when the net external force is zero, an object may travel with non-zero velocity. A rain drop falls downwards with a constant velocity. The net force on the drop is zero because the weight of the drop is balanced by the upthrust and the viscosity of air. When a carpet is beaten with a stick, dust comes out.
