A cyclist competes in a one-lap race around a flat, circular course of radius, r. Starting from rest and speeding up at a constant rate throughout the race, the cyclist covers the entire course in a time (delta)T. The mass of the bicycle (including the rider) is m. What is the magnitude of the net force acting on the bicycle as it crosses the finish line?

Express the net force in terms of r, (delta)t, m, and "pi".

In class we are working on using the radial and tangental and I do not need to solve the problem, just need to write out the net force with the above variables.
thanks!

In a military test, a 575 kg unmanned spy plane is traveling north at an altitude of 2300 m and a speed of 500 m/s. It is intercepted by a 1360 kg rocket traveling east at 775 m/s. If the rocket and the spy plane become enmeshed in a tangled mess, where, relative to the point of impact, do they hit the ground?

_______ km
_______ angle north of east


Thanks

two resistors and an ammeter connected in series to a 6v DC supply. the distance of the ammeter is so small that it can be ignored.

What is the combined resistance of the 8ohm and 4 ohm resistors in series...

what is the current supplied by the 6v DC supply?

state the value of the current recorded by the ammeter

l----Q-l___8ohm___l----l
l ...............................l
+P ............................ l
6V.............................(A)
-R ..............................l
l ................................l
l--------S-l__4ohm__l---l


state the value of the current in section PQ of the curcuit

state the value of the current in section SR of the circuit



Ignore the dots in the diagram the thing would not accept my spaces

An airliner lands with a speed of 47.0 m/s.
Each wheel of the plane has a radius of 1.25 m and a moment of inertia of 110 kg*m^2. At touchdown the wheels begin to spin under the action of friction.
Each wheel supports a weight of 1.40X10^4 N, and the wheels attain their angular speed in 0.53 s while rolling without slipping.

QUESTION:
What is the coefficient of kinetic friction between the wheels and the runway? Assume that the speed of the plane is constant.

You can never catch up.

In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.

----------------------------------------------------
You cannot even start.

That which is in locomotion must arrive at the half-way stage before it arrives at the goal.
-----------------------------------------------------

You cannot even move.

If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.

jump altogether? The answer I got is 5 ft based on Pythagorean theorm a^2+b^2=c^2. But... what is someone else dives at the same angle and enters the water 6 ft. from the base of the wall. How high would their diving block be? It can't be the same height to maintain the same angle. How do I figure this out?
