What Force sh...

Question

What Force should be applied on an object of mass 50kg .to make it accelerate upto50 kg /hr

Open in App

Solution

first of all the unit of acceleraion is wrong it should be m/s^2 and if it is 50 m/hr^2 then converting gives
50/3600 m/s^2
= 0.0138 m/s^2

now

Force = Massacceleration
so Force = 500.0138 = 0.69 N
