Question

body of mass 5 kg is moving with a velocity of 10 metre per second up for supply to it is so that in 25 second it attains a velocity of 35 metre per second calculate the value of the force applied

Answer 1

Howdy!!

your answer is ---

Given ,
mass of body m = 5kg
initial velocity u = 10m/s ,
final velocity v = 35m/s
& time period t = 25 second


now , we known that

force = mass × acceleration
or , F = m × a

=>
$f = m \times a \\ = > f = m \times \frac{v - u}{t} \\ = > f = 5 \times \frac{35 - 10}{25} \\ = > f = 5 \times \frac{25}{25} \\ = > f = 5 \times 1 = 5newton$


hence, force = 5N
