Question

Bonita (mass of 60 kg) is stuck, motionless, on a frictionless frozen lake. The only thing she has on her is her iPhone 13 (mass of 175g). She throws her phone, knowing that she if she exerts a force on her phone, it will exert a force back on her (according to Newton's third law), sending her sailing her backwards and towards the safety of the lakeshore. She has a good arm, so she throws the iPhone with a speed of 30 m/s.
With what speed does Bonita travel after throwing her phone and how much energy did Bonita expend throwing her phone (assuming 100% efficiency)?
