(4) A bicycle travels along a straight road. Let p (t) = The position of the bicycle (in feet) at time t(in seconds) v (t) = The velocity of the bicycle (in feet/sec) at time t (in seconds) a (t) = The acceleration of the bicycle (in feet/sec2 ) at time t (in seconds) ( some of these questions require you to write an integral, some don’t; only use an integral to answer a questions if you need to) (a) Using v (t) (and no other variables) write an expression representing the average velocity of the bicycle from t = 20 seconds to t = 50 seconds. Include units in your answer. (b) Using v (t) (and no other variables) write an expression representing the displacement of the bicycle from t = 20 seconds to t = 50 seconds. Include units in your answer. (c) Using v (t) (and no other variables) write an expression representing the average acceleration of the bicycle from t = 20 seconds to t = 50 seconds. Include units in your answer. (d) Using p (t) (and no other variables) write an expression representing the average velocity of the bicycle from t = 20 seconds to t = 50 seconds.

You are driving along straight road. You cover 200 miles in 4 hours? Does that mean that your speedometer read 50 mph for your entire trip? Is is necessary that your speedometer register 50 mph at least once during the trip? Use math to explain your answer. I understand that your speedometer would not be 50mph for the entire trip, but I am not sure how to explain it using math.

3. An ambulance travels back and forth at a constant speed along a road of length L. At a certain moment of time, an accident occurs at a point uniformly distributed on the road. [That is, the distance of the point from one of the fixed ends of the road is uniformly distributed over (0, L).] Assuming that the ambulance’s location at the moment of the accident is also uniformly distributed, and assuming independence of the variables, compute (a) The...

a stunt driver's car is moving at 24.2 m/s along a straight road. The road comes to an abrupt stop 21.2 m before a drop off. The coefficient of friction of the road is 0.712, and the coefficient of friction of the dirt between the road and the drop off is 0.426. What is the minimum distance at which the driver can behin to apply the brakes and still prevent himselff from going over the edge?
