A car is going 60mph (88ft/second) when it suddenly applies the brakes at time t=0 and skids (with constant deceleration) for 176 ft until it stops. What was the rate of deceleration? How long did it take before the car stopped?
An arrow was shot straight up from the ground at time t=0 seconds with an initial velocity of 49 m/sec. Assuming that the free-fall acceleration is -g=-9.8 m/sec^2, determine its maximum height, and when it hits the ground.
