Question

a body starts from rest and Rolls down a hill with a constant acceleration if it travels 200 metre in 10 second calculate the force acting on the body if its mass 10 kg​

Answer 1

Answer:Given data:

Mass of body(m)=10 kg

Distance(S)=200 meter

Time(t)=10second

1) We have to find the acceleration of the roll body

So from the equation of motion  

$So from the equation of motion S=ut+ 1/2at^{2} ​ whereu=0$

, whereu=0

2) Force acting on rolling body

So,from newton's 2  nd  law of motion

F = ma

Explanation:

Answer 2

Answer:

40 N

Explanation:

formulas used -

#force = mass x Acceleration

and

#second equation of motion

s = ut + 1/2 a t^2

(1) first find acceleration

(2) then substitute acceleration in the force formula
