A car is going with a constant tangential acceleration (i.e. increasing speed) in a circular path. As seen from above, the path is counter-clockwise. It crosses the point 'A' at time 0.00, at which point its speed is known. Find the direction of its centripetal acceleration at some time after it crosses the point A:Write your answer in degrees. Given: Speed when it crosses point 'A' - V-3.6 m/s, tangential acceleration a 3.6 m/s2, radius of path...

A motorist traveling with a constant speed of 15m/s passes a school-crossing corner, where the speed limit is 10m/s
A motorist traveling with a constant speed of 15m/s passes a school-crossing corner, where the speed limit is 10m/s. Just as the motorist passes, a police officer on a motorcycle at the corner starts off in pursuit with constant acceleration of 3m/s^2. (a)How much time elapses before the police catches up the motorist? (b)What is the officer's speed limit at that point? (c)What is the total distance each vehicle has traveled at that point?

A person driving her car at a speed v= 38.0 km/h approaches an intersection just as the traffic light turns yellow. She knows that the traffic light lasts only 1.5 sec, before turning to red, and she is a distance d= 30.0 m away from the near side of the intersection (see figure). The width of the intersection is w = 13.9 m. Her car's maximum deceleration is -5.50 m/s, and its maximum acceleration is 0.950 m/s2. - W -...
