A uniform ladder of mass 17 kg and length 6 m leans against a smooth wall at an angle
67° with respect to the ground. A person of
mass 58 kg climbs up the ladder to a point
two-thirds of the way to the top. Assume
that there is no friction between the top of
the ladder and the wall.
Compute the minimum coefficient of static
friction between the ladder and the ground
that would prevent the ladder from slipping.

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
