Garen observed his athletic friends , Aya and Marisa, run. The two girls ran in a 1.5-km straight dirt road. Marisa was a given a ten-second head-start. When Aya ran, she caught up with Marisa, who ran at 3.75 m/s. Both of them finished the 1000 m run, with Aya measured to finish the track at 375 seconds. 1. How fast was Aya? 2. How far did Marisa run after ten seconds? 3. Find the time Aya caught up alongside Marisa.

How far did Marisa run after ten seconds? Find the time Aya caught up alongside Marisa. Find the distance where both runners met. How long did Marisa run before she could finish the sprint? Jayce threw his softball high in the air as Yukari looked down from her two-storey home to see how high he threw it. Jayce threw his ball high enough to reach the floor of the second storey. If Jayce threw the ball at an initial velocity of 30 m/s, and an initial height of 1.22 m, with one storey equivalent to at least 3.05 meters. How fast is the ball after 0.2 seconds? With the initial values, how high will the ball fly after 3 seconds?

Kenny is climbing the stairs of his apartment building for exercise. Kenny weighs 83 kg and the height of a single step on the staircase is 11 inches. He climbs a flight of stairs in 4.0 seconds. a.) calculate the rate at which the stairs can be climbed considering the given information (stairs per second). b.) How long can kenny sustain this pace (so like, continuously climbing the stairs and not leaping up a bunch of stairs at one instant)? c.) Why does Kenny descend stairs at a faster rate for a nearly unlimited time although very similar forces are exerted descending as they are ascending?(This points to a fundamentally different process for descending versus climbing stairs.)
Jayvee is travelling on his bicycle in 12.5 m/s and passes by a stationary truck. After Jayvee passesby the car, the car accelerates at 3.6 m/s2. Solve the following problems:a.

Clarissa is running at 5m/s to catch the school bus, which is stopped to a nearby bus stop. When Clarissa is still 40 meters away from the bus, the bus is already moving with a constant acceleration of 0.170 m/s2 . A. Compute the time and the distance does Clarissa have to run before she can overtake the bus. B. At the instant she reaches the bus, how fast is the bus moving?
