Steps appreciated~

1. If the diameter of a monster truck tire is 3.5 m and it makes one rotation every 5 seconds, how far does the tire

roll in 1 minute?

--------------------------------------

2. At t=0 a car is due 2 km north of you heading west moving 13 km/s after 1.5s. What is the angle in radians between you and the car from where the car was at t=0?

a) 2.306 rads

b) 0.9475 rads

c) 2.936 rads

d) 1.468 rads

1. pi*D*(60/5 revolutions) = 131.9 meters

2. Check your problem statement again. No car can travel 13 km/s. That is more like the velocity of a launched rocket. If you meant 13 m/s, the car would only move 19.5 m in 1.5 s, and the angular displacement would be smaller than any of your choices.

My guess is that you copied both the speed and time dimensions wrong.

For 1, I got the same answer however, the book says 263.89 m
