Chapter 2, Problem 24CQ
The severity of a fall depends on your speed when you strike the ground. All factors but the acceleration due to gravity being the same, how many times higher could a safe fall on the Moon be than on Earth (gravitational acceleration on the Moon is about 1/6 that of the Eat)?

When we estimate distances from velocity data, it is sometimes necessary to use times
t0, t1, t2, t3, . . .
that are not equally spaced. We can still estimate distances using the time periods
Δti = ti − ti − 1.
For example, a space shuttle was launched on a mission, the purpose of which was to install a new motor in a satellite. The table provided gives the velocity data for the shuttle between liftoff and the jettisoning of the solid rocket boosters. Use these data to estimate the height, h, above Earth's surface of the space shuttle, 62 seconds after liftoff. (Give the upper approximation available from the data.)h = ft

A thoughtful person on a bridge reflecting on his awesome Physics class sees a
small stone by his feet. Hmm, he thought to himself. Using his foot he slowly
nudged the stone off the surface of the bridge and using his cell phone he timed
how long it took to hit the water, about 1.75 s. How high (m) is the bridge
above the water? (neglect air resistance)
The acceleration due to gravity on the surface of a planet depends on the mass and size of the planet; therefore, other planets will have accelerations due to gravity other than 9.8 m / s2. Imagine an astronaut standing on an alien planet, which has no atmosphere, and throws a stone with a velocity of 7.35 m / s in a horizontal direction, dropping it at a height of 1.40 m above the surface of the planet. The rock hits the surface at a horizontal distance of 9.50 m from the astronaut. Find the magnitude of the acceleration due to gravity, in m / s2, on this alien planet.
