Question

You are pushing a friend on a sled. You push with a force of 20N. Your friend and the sled together have a mass of 60kg. Ignoring friction, what is the acceleration of your friend on the sled?

Answer 1

According to Newton's 2nd law of motion, F = ma. a = F /m = 20/60 = 0.33m/s^2. Hope it cleared your doubt.

Answer 2

The acceleration of your friend on the sled can be given by newton's second law of motion and it is $0.33 m/s^{2}$.

What is acceleration?

Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities as it has both magnitude and direction.

It is given by

$a = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}$

Where,

$a$ = average acceleration

$v$ = final velocity

$v_{0}$ = starting velocity

$t$ = elapsed time

What is newton's second law of motion?

Newton’s second law state the changes that a force can produce on the motion of a body with a mass.

For a body with mass m constant, it can be written in the form

$F = ma$

Where

$F =$ force

$a =$ acceleration

Given

$F = 20 N$

$m = 60 Kg$

$F = ma\\20 = 60*a\\a = 0.33 m/s^{2}$

The acceleration of your friend on the sled is $0.33 m/s^{2}$.
