A car accelerates from rest for 5 seconds at 8 mi/hr/s, heading west. It then continues without acceleration for 10 seconds. The brakes then slow the car to half its previous speed in 4 seconds and then to a stop in 3 more seconds. Graph the speed of the car as a function of time.

Ralph is driving at a constant 70.0 mi/hr (31.3 m/s) along a straight section of Route 3 North. The car directly ahead of him is also moving at 70.0 mi/hr. The front bumper of Ralph's car is located 12.00 m from the rear bumper of the car ahead when, at t0, the driver of the car ahead applies his brakes and begins to slow down at a steady rate of 6.00 2, towards the posted speed limit of 50.0 mi/hr...

The Tesla Model X is an electric car that can travel approximately 238-295 mi on a full charge. Tesla dealers claim the time it takes to fully recharge depends on the percent depleted, but is approximately a normal random variable X with mean u = 2.5 hours and standard deviation o = 0.75 hour (on a 240-volt line). Suppose a random Tesla Model X is connected to a home recharging station. (c) If the amount of time to fully recharge...

4. A bicyclist makes a trip that consists of three parts, each in the same direction (due north) along a straight road. During the first part, she rides for 22 minutes at an average speed of 7.2 m/s. During the second part, she rides for 36 minutes at an average speed of 5.1 m/s. Finally, during the third part, she rides for 8.0 minutes at an average speed of13.0 m/s.

Problem 1) A car starts from rest at x 0 and 0, travelling in a straight line. The car speeds up and then slows down until it comes back to rest at a distance of 0.900 km from where it started. For the first quarter of the distance, its acceleration is +2.25 m/s2, while for the last three quarters of the distance its acceleration is -0.750 m/s2. (a) Find the travel time for the entire trip. (b) Find the maximum...
