- You and a friend ride your bikes to a restaurant across town. Both of you start at the same instant from your house, you riding 10 m/s and your friend riding 12 m/s. During the trip your friend has a flat tire and that takes him 8 minutes to fix. He then continues the trip at the same speed of 12 m/s. If the distance to the restaurant is 10 km, who gets there first?arrow_forward8. A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 30 m/s² for 30 s, then runs out of fuel. Ignore any air resistance effects. (a) What is the rocket's maximum altitude? (b) How long is the rocket in the air before hitting the ground?arrow_forward. (a) A car is traveling over a circular hill with a speed v.
