Q1. A large truck tire is inflated to a gauge pressure of 84 psi. The total area of one side wall of the tire is 1,600 in. what is the outward force on the sidewall by reason of the air pressure?
Q2. What should be the spring constant of a spring designed to bring a 1500 car to rest from a speed of 75 so that the occupants undergo the maximum acceleration of 5.0?
Q3. Co-60 is often used as a radiation source in medicine. It has a half-life of 5.25 years. How long, after a new sample is delivered, would the activity have decreased to about 1/3 its original value?
