Two highways intersect as shown in the figure. At the instant shown, a police car P is distance dP = 870 m from the intersection and moving at speed vP = 87 km/h. Motorist M is distance dM = 560 m from the intersection and moving at speed vM = 56 km/h. What are the (a) x-component and (b) y-component of the velocity of the motorist with respect to the police car? (c) For the instant shown in the figure,...

Two highways intersect at right angles. From
out point of view, Car A on one highway is
0.5 km from the intersection and is moving toward it at 96 km/hr,
while car B on the other highway is 1 km from the intersection and
is moving away from it at 88 km/hr. We would
therefore call the position and velocity
of car A to us to be
Position: ?⃗? ?? ?? = (0.5...

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?
What is the position of the car when the officer catches up to
it?

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...

You are arguing over a cell phone while trailing an unmarked police car by 32 m. Both your car and the police car are traveling at 110 km/h. Your argument diverts your attention from the police car for 2.5 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.5 s, the police officer begins emergency braking at 5 m/s2. (a) What is the separation between the two cars...

You are arguing over a cell phone while trailing an unmarked police car by 36 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 2.0 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.0 s, the police officer begins emergency braking at 5 m/s2. (a) What is the separation between the two cars...

Car A goes along a curve of 100 m radius at a speed of 10 m/s and increasing at the rate of 5 m/s2 whereas Car B is moving along a straight stretch of road with a velocity of 18.5 m/s and increases at a rate of 2 m/s2. The position of both cars A and B at a particular instant is as shown in Figure Q2(a). Calculate the acceleration of car A relative to car B and their relative...
