Q. What is the force of air resistance on a 100 kg sky-diver who is falling with a constant acceleration of 4m/s/s?
Q. A 55.0 kg pole vaulter running at 8.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.0 m/s and disregarding air resistance, how high was the jump?
What minimum force is necessary to start the block moving up the wall? (Hint: The static frictional force is now directed down the wall.)
A soprano saxophone is an open pipe. If all keys are closed, it is approximately 65 cm long. Using 343 m/s as the speed of sound, find the lowest frequency that can be played on the instrument.
Mrs. Smith has returned to work and feels well. She does not know why she needs to have periodic blood tests due to the warfarin. What is your explanation to Mrs. Smith.

A car dealer claims that his product would accelerate at a constant rate from rest to a speed of 200 km/hr in 8s. What approximate distance will the car travel.
Law of Gravitation- Find out an expression for the magnitude of the initial velocity that a projectile should possess in order to leave the earth when air friction is neglected. The gravitational constant for g is, G = 6.67428*10^-11 m^3 Kg^-1 s^-..
A car takes 9 s to go from v = 0 to v = 75 m/s at approximately constant acceleration. If you wish to find the distance travelled using the equation d = 1/2 at2, what value should you use for a.
A 15.0 m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes a 60.0 angle with the horizontal. Find out the horizontal and vertical forces the ground exerts on the base of the ladder when an 800 N fire-fighter is 4.00m f..
The two forces in each pair could have different physical origins (for instance, one of the forces could be due to gravity, and its pair force might be due to friction or electric charge).
