Answer:
5.7 m/s
Explanation:
The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:
1) The Physical principle: conservation of momentum.
If there is no net external force operating on a system, so the system's total momentum is conserved
The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:
P = mv.
2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.
Based on this, the calculation is as follows
Momentum before the collision:
= 340 kg m/s
Now Momentum after the collision:
= 5.7 m/s
