You throw a 134 g ball straight up to a height of 43.0 m. (a) Assume that the displacement of your hand is 0.70 m as you throw the ball straight up. How long is the ball is in your hand? (b) Calculate the average force exerted by your hand while you are throwing it.

A physics student playing with an air hockey table (a frictionless surface) finds that if she gives the puck a velocity of 5.30 m/s along the length (2.80 m) of the table at one end, by the time it has reached the other end the puck has drifted 5.19 cm to the right but still h...

Real rate = 11-3.8 = 7.2% 1,500,000/(1+0.072)^40= 92960.80 To check this is correct you can do: 92960.80*(1+0.072)^40= 1,500,000

If the interest on a long-term Canadian(3/8%) investment is compounded continuously, how long will it take the value of an investment to triple? (Give the answer correct to two decimal places.) Got 19 years--its wrong, can't find reason. Thanks.

you get this one yet? can't figure it out either..

If a bicyclist of mass 68.0 kg (including the bicycle) can coast down a 7.00° hill at a steady speed of 6.20 km/h because of air resistance, how much force must be applied to climb the hill at the same speed (and the same air resistance)?

A 61.7 kg person jumps from rest off a 2.98 m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.19 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This forc...
