Assume the area of an eardrum is about 4.9 x 10^-5 m^2. Find the sound power (energy per second) incident on an eardrum at the threshold of hearing (Io = 1 x 10^-12 W/m^2) in units of W.

Also, find the sound power incident on the eardrum at the threshold of pain (I1 = 1 W/m^2) in units of W.

A large globe, with a radius of about 5m.
Imagine that such a globe has a radius R and a frictionless surface. A small block of mass m slides starts from rest at the very top of the globe and slides along the surface of the globe. The block leaves the surface of the globe when it reaches a height h above the ground.

Use the law of conservation of energy to find Vcrit??

I found Using Newton's 2nd law, that Vcrit the speed of the block at the critical moment when the block leaves the surface of the globe is V=sqrt(g(h-R))

Im trying to do some homeowrk but im stuck on this question can anyone help please.

A student standing on a scale in an elevator at rest sees that his weight is 840 N. As the elevator rises his weight increases to 1050 N, then returns to normal. When the elevator slows to a stop at the 10th floor his weight drops to 588 N then returns to normal. Determine the acceleration at the beginning and end of the trip.

A child riding a bike has a total mass of 40.0 kg the child approaches the top of a hill that is 10 m high and 100m long at 5.0m/s. If the force of friction between the bicycle and the hill is 20N, what is the childs velocity at the bottom of the hill? (Disregard air resistance g= 9.81 m/s^2)

A. 5.0m/s
B. 10.0 m/s
C. 11m/s
D. Child stops before reaching the bottom.





i have already posted this question and thanks to the guy who answered but i need some more answers so i can decided what i'm going to do.
