A body P of mass 5kg moving with a velocity of 30M/s collids with another body q moving in opposite direction with a velocity of 20m/s.If the bodies now move in the direction of P at velocity 10m/s.calculate the mass of q
Answered by Chanz
Assuming inelastic
m1v1 + m2v2 = (m1+m2)vf
5(30) + m2(-20) = (30+m2)10
Solve for m2

0.15m/s


Answered by shamweelu
m1v1=m2v2
5×30=m2×20
m2=150/20
m2=7.5kg

m1×v1+m2×v2 =(m1+m2)
5×30+q+20=(q+5)
150+q×20=q+5=10

150+20+10=2q+5
180=2q×5
180/10=10/10
q=18 kg
