A kangaroo jumps up with an initial velocity of
36 feet per second from the ground (assume
its starting height is O feet). Use the vertical
motion model, h = -1612 + vt + s, where y
is the initial velocity in feet per second and s
is the height in feet, to calculate the amount of
time the kangaroo is in the air before it hits the
ground again. Round your answer to the
nearest tenth if necessary.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
