A 37 kg child uses a pogo stick to bounce up and down. The spring constant, k, of the toy equals 9,000 N/m.
(a) By how much would the spring be compressed by the child if she simply balanced herself vertically on the pedals of the stick? (Give your answer in cm.)
(b) How much energy (in J) is stored in the spring under this circumstance?
An ice block is pushed horizontally on a frictionless surface with initial velocity v0. At some point, it comes to the nearly semicircular bump with a radius R=0.42m and the height h=0.33m above the ground.
An extremely thin film of soapy water (n = 1.26) sits on top of a flat glass plate with n =1.51. The soap film has a red color when viewed at normal incidence. What is the thickness of the film? (Wavelength of red, or lambda = 640nm.)
A baseball pitcher throws a 44 m/s fastball. The baseball bat reverses the ball's velocity and it leaves the bat at 56 m/s. What was the average force on the 0.145 kg baseball through the contact time of 15 ms?
