Chapter 2, Problem 56PCE
Predict/Calculate You are driving through town at 16 m/s when suddenly a car backs out of a driveway in front of you. You apply the brakes and begin decelerating at 3.2 m/s2. (a) How much time does it take to stop? (b) After braking half the time found in part (a), is your speed 8.0 m/s, greater than 8.0 m/s, or less than 8.0 m/s? (c) Find your speed after braking half the time found in part (a).

A bike and a tricycle travels on the same road but on opposite direction. The bike jolts from rest at t=0 and moves towards east with a constant acceleration of 6ft/s^2 until it reaches a speed of 50ft/s. Afterwards it maintains this speed. On the other hand, when t=0, the tricycle located 6000ft from the bike is traveling at a constant speed of 30ft/s. Determine the time and the distance traveled by the bike and tricycle when they pass each other
I need help witth answering the time elapsed when they pass each other. the distance traveled by the bike when they pass each other and the distance traveled by the tricycle when they pass each other.
Is it possible for an object to be at zero velocity when its acceleration is not zero? Explain with an example
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, of 295.38 km/h. The one-way course was 8.00 km long. Acceleration rates are often described by the time it takes to reach 96.0 km/h from rest. If this time was 4.00 s and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?
