Question

Tony Stark is inside his Iron Man suit and standing
on a frictionless surface. His combined weight
with his suit is 150 kg. He suddenly jumps out
of his suit at 2 m/s. If his own mass is 85 kg, at
what velocity will his Iron Man suit move when he
jumps forward?​

Answer 1

Explanation:

Every action has equal and opposite reaction

mv=mu

mass of suit+Tony's weight=150 kg

mass of suit= 65 kg

85*2=65*x

(85*2)/65=x

approximately 2.6 m/s
