12-B12 This car is driving up the hill shown. When he passes the origin he is travelling 35 m/s and thereafter his x velocity is defined as Vx=35-1.2t. At t=15 seconds, determine The position (x,y) and the x,y components of both velocity and acceleration. • What does his speedometer read at that point in km/hr? y = 0.0003.r

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...

A ranger in a national park is driving at 53 km/h when a deer jumps onto the road 75 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -3.2 m/s^2. What is the maximum reaction time allowed if the ranger is to avoid hitting the deer? Answer in units of s.

A motorcycle cop is parked on the side of the road when a woman driving a red Ferrari zooms by at 90.0 km/h. After a few attempts to get his cycle started, the officer roars off 2.00 seconds later. The officer has a top speed of 100 km/hour, and the state line is only 2.00 km away. The cop wishes to reach the speeder just as she reaches the state line. The question is if the officer is to reach...
