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.
