a car is taveling at 80 km/hr in a school. A police car is at rest in the parking lot of the school. It takes the policeman 0.5 sec to react before he begins accelerating after the speeder with an acceleration of 8 m/sec square. A) how far has each car traveled when the police car catches the speeder B) how fast is the police car going when it catches the speeder?

Suppose that instead of moving at a constant speed, the car in
VP 2.9.1 begins to accelerate at 1 m/s2 at the
moment it passes the school crossing. How much time elapses before
the officer catches up to the car?

Problem 2.38 An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 139 km/h. Part A Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator: if the police car's acceleration is 2.70 m/s, how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)? Express your answer with the appropriate units. t = 10 Submit...

Please answer the following physic questions. Thank you! 1. A dog sees a flowerpot sail up and then back past a window 5.0 ft high. If the total time the pot is in sight is 1.0 seconds, find the height above the window that the pot rises. 2. An elevator ascends with an upward acceleration of 4.0 ft/s2. At the instant its upward speed is 8.0 ft/s, a loose bolt drops from the ceiling of the elevator 9.0 ft from...

you are given 4 vectors with equal magnitudes. under what conditions will their sum be zero? if a vector has an equal, positive x and y components, what are the angles it makes with the axes? A superhero jumped horizontally from a 31 m high rooftop to the ground immediately after he spotted a child walking towards a busy street all alone. Fortunately, he lands on the street just next to the child in 2.5s and the child is rescued!...

1) A car is traveling at a steady 77km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 7.3m/s2 . a)How much time elapses before the motorcycle is moving as fast as the car? b)How far is the motorcycle from the car when it reaches this speed? 2)A gannet is a seabird that fishes by diving from a great height. If a gannet hits the water at 32m/s...
