A car starts moving and runs a distance of 129 meters in 14 seconds with a constant acceleration.
Then it keeps moving with a constant velocity for 12 seconds.
Finally, it stops by braking 16 seconds after.
What's the total distance that the car made?

P2.4-4) A car initially traveling at 60 mph coasts for 5 seconds. Due to friction and wind resistance, the car decelerates while coasting at a rate of 1 ft/s2. After the 5 seconds of coasting, the driver applies the brakes and decelerates at a constant rate eventually bringing the car to a stop. If the total time that the car travels is 8 seconds, determine the car's braking acceleration. Given: Find: Solution: Draw the acceleration and velocity curves. v (ft/s)...

A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
