Answer:
O The speed of the ball from Sean's reference frame would be greater than the speed of the ball from Rhea's reference frame.
Explanation:
Say the ball is kicked at 10 m/s and Rhea is running 3 m/s
Sean would see the ball approach at 10 m/s and Rhea approach at 3 m/s
Rhea would see Sean approach at 3 m/s and the ball depart at 10 - 3 = 7 m/s
The ball would see Sean approach at 10 m/s and Rhea depart at 7 m/s
Relative velocity relationships we can shorten the correct answer is:
- The speed of the ball from Sean's reference frame would be greater than the speed of the ball from Rhea's reference frame.
Velocity is defined as the change in position with respect to time, this definition implies that there must be a reference system with respect to which to carry out measurements.
The relative velocity occurs when we have two or more bodies and it is the speed of a body measured by the observer in the other body. To find this velocity using addition vector the body speeds must be performed according to each reference system.
v_{ba} = v_b - v_a
Where v_{ba} res relative velocity of b with respect to a, v_b is the speed of body b and v_a is the speed of body a.
Let's apply these definitions of the relative velocity at this case Sean is stationary therefore his velocity is zero, Rhea is moving so his velocity is v_r and the ball has a velocity v
Let us write the relative velocity, in the adjoint you can see a diagram of the movement, the system that is this movement is S'
v_{bs} = v_{br} - _v{rs}
Where
v_{bs} Speed of the ball with respect to Sean
v_{br} Velocity of the ball with respect to Rhea
v_{ra} Rhea's speed respect to Sean
Rhea walks up to Sean her speed is negative
v_{bs} = v_{br} + | v_{rs} |
Consequently the speed measured by Sean is greater than the speed measured by Rhe
In conclusion using the relative velocity relationships we can shorten the correct answer is:
- The speed of the ball from Sean's reference frame would be greater than the speed of the ball from Rhea's reference frame.
