Question

A force of 30 N acts on a body of 5 kg for 2 seconds then the acceleration of the body is

Answer 1

Answer:

Acceleration of the body is $6ms^{-2}$.

Explanation:

Using Newton's second law,

$Force=Mass\times Acceleration$

Substituting the values

$30=5\times a$

 $a=\frac{30}{5}$

 $a=6ms^{-2}$

Answer 2

Answer: Acceleration of the body is $6m/s^2$.

Given - Force of $30N$ acts on a body of $5kg$ for $2$ Seconds.

Find - The acceleration of the body,

Solution- In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Now, $F=30N,$ mass of body $=5kg$

$F=ma\\30=5\times a\\a=\frac{30}{5}\\ a=6m/s^2$

So, the acceleration of the body is $6m/s^2$
