Question

a body of mass'm' kg starts from rest and travels a distance of 's' m in 't' seconds. find the force​

Answer 1

Explanation:

first of all, the formula to find force is mass × acceleration.

but acceleration is not found.

and the formulafor accelerationis distance / time. which is given as s/t

so therefore force = m×s/t

=ms/tH.

SURE IT HELPS. PLS MARK BRAINLLIEST

Answer 2

Answer:

We know a particle starting from rest with constant acceleration(a),then distance travelled(s),is given by

Explanation:

$s = \frac{1}{2} {at}^{2} \\ a = \frac{2s}{t {}^{2} }$

So the force is

$ma = m \frac{2s}{ {t}^{2} }$

a)is correct answer.
