From the calculation, Sheila’s velocity immediately after she is thrown from the bike is 5.7 m/s.
<h3>What is momentum?</h3>
Momentum is the product of mass and velocity. We know that the momentum before collision is equal to the momentum after collision.
Hence;
Momentum before collision = 340 kg • m/s.
Momentum after collision = 60v
Thus;
340 kg • m/s = 60v kg • m/s
v = 340 kg • m/s/60 Kg
v = 5.7 m/s

Answer:
Both physical and chemical changes
'A' and 'C' talk about energy being created and destroyed. That can't happen.
'D' trailed off in the middle, and we don't know WHAT it was talking about.
'B' is the only correct statement.
Answer:
First let's find the work.
Work = Force*Displacement
= 20*5
= 100 Joules
Power = Work/Time
= 100/4
= 25 Watts
