Question
A shopping cart accelerates 0.5 m/s2 when a net force of 8 N is applied to it. What is the mass of the shopping cart?
4 kg
0.06 kg
8.5 kg
16 kg
can someone explain this to me?

Third law is
Force = rate of change of momentum
= change of m V / change it time
if m is constant
Force = m * change of V / change in time = m * acceleration
here
8 Newtons = m * ( 0.5 meters/ second/ second)
m = 8/0.5 = 16 kg
Force = rate of change of momentum
= change of m V / change it time
if m is constant
Force = m * change of V / change in time = m * acceleration
here
8 Newtons = m * ( 0.5 meters/ second/ second)
m = 8/0.5 = 16 kg
