Question

Which statement about these racers is TRUE? Assume all the racers start at the same time and the same location and that the initial velocity of Racer 3 is zero.

a. The speed of Racer 2 is larger than the speed of Racer 3 at t = T/2
b. Racer 3 is ahead of Racer at t = T/2
c. Racer 3 is ahead of Racer 1 at t = T/2
d. The speed of Racer 3 s larger than the speed of Racer 1 at t = T/2
e. The speed of Racer 2 is larger than the speed of Racer 1 at t = T/2

Answer 1

I believe it's c a or d,

Answer 2

Racer 3 is ahead of Racer 1 at t = T/2.

Step-by-step explanation:

In this scenario, all the racers start at the same time and location. The initial velocity of Racer 3 is zero, meaning Racer 3 starts from rest.

Based on this information, we can conclude that statement c is true: Racer 3 is ahead of Racer 1 at t = T/2. Since Racer 3 starts from rest while Racer 1 is already moving, Racer 3 will have covered less distance by the halfway point of the race, making Racer 3 ahead of Racer 1.

Therefore, the correct answer is c.
