Challenging Physics problem of the week. Do as much as you can. Thanks

In summary: Calculate the time using the given speed and distance.In summary, the conversation involves two different problems. The first problem focuses on Tom Jager's swimming speed and a potential race against Michael Phelps. The second problem involves a car's acceleration and final speed. In the first problem, Tom's average speed is calculated to be 2.29 m/s. If he could maintain this pace, it would take him approximately 23.3 minutes to swim one mile. In the race against Phelps, Phelps would win by a distance of 0.5 meters. In the second problem, the car's average acceleration is calculated to be 26.67 (mi/h)/s or 12 m/s^2. After 1.65

Homework Statement



1. Tom Jager swam the 50 m free in 21.81 seconds.

a. Calculate Tom's average speed
b. If Tom could continue this incredible pace, how long (in minutes) would it take him to swim one mile?
c. Tom races Micheal Phelps. If Phelps swims at an average of 2.35 m/s and the race is 50 meters in length, who wins and by what distance?

2. A car can accelerate from 0-60 mph in 2.7 seconds.

a. Calculate the average acceleration of this car in (mi/h)/s and in m/s^2
b. How fast will the car be traveling after 1.65 seconds
c. How long would it take the car to accelerate from 10 mi/h to 35 mi/h?

Hi geo951,
Welcome to PF.
We are here to help the students in their home work difficulties, not receive the challenges. If you have any difficulties in the above problems, show your attempts.

1a. 50m/21.81= 2.29 m/s

I just need help on how to do the rest. You do not have to do it all for me.

Write down the relevant kinematic equations. Find the conversion of mile to meter.
