2.70 Egg Drop. You are on the Figure P2.70
roof of the physics building, 46.0 m
above the ground (Fig. P2.70). Your
physics professor, who is 1.80 m tall,
is walking alongside the building at
a constant speed of 1.20 m/s. If you
wish to drop an egg on your profes-
sor's head, where should the profes-
sor be when you release the egg?
Assume that the egg is in free fall.
2.71 CALC The acceleration
of a particle is given by ax(t) =
-2.00 m/s² +(3.00 m/s³)t. (a)
Find the initial velocity Vox such that
v = 1.20 m/s

One has to push down a ball with a force of 470 Newtons in order to hold the ball still, completely submerged under the surface of the water. What is the volume of the styrofoam ball in cubic meters? Use 997 kg/m3 as the density of water, 95 kg/m3 for the density of the styrofoam, and g = 9.8 m/s2.

- Use relevant diagrams where necessary and go through it in detailsarrow_forwardYour blood pressure (usually given in units of "mm of Hg") is a result of the heart muscle pushing on your blood. The left side of the heart creates a pressure of 115 mm Hg by exerting a force directly on the blood over an effective area of 14.5 cm2. What force does it exert to accomplish this? (Give your answer as the number of Newtons and note that you will need to do some unit conversions.)arrow_forwardWhat is the absolute (total) pressure experienced by a diver at a depth of 17 meters below the surface of a lake?
