I will be greateful to you,if you kindly hep me to solve the below problem:
When a horizontal force of 200N is applied on a body ,he acceleration produced in it is 1.5m/s2.when the force is 300N the acceleration produced in it is 2.5m/s2.find the mass of the body.
i have solved the above problem like this:
F=ma
(200+300)N=m*(1.5+2.5)m/s2
500N=m*(4)m/s2
500N=4m/s2*m
4m/s2*m=500
m=500/4
m=125kg
therefore mass of the body is 125kg.
