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.
