Extra Practice Problems - Set 03: Rectilinear Motion - Part 2
Question 1 [P /027]: A vacuum‐propelled capsule for a high‐speed tube transportation system of the
future is being designed for operation between two stations A and B, which are 10 km apart. If the
acceleration and deceleration are to have a limiting magnitude of 0.6𝑔 and if velocities are to be
limited to 400 km/h, determine the minimum time 𝑡 for the capsule to make the 10‐km trip.

Question 2 [P /028]: The 230,000‐lb space‐shuttle orbiter touches down at about 220 mi/hr. At 200
mi/hr its drag parachute deploys. At 35 mi/hr, the chute is jettisoned from the orbiter. If the
deceleration in feet per second squared during the time that the chute is deployed is −0.0003𝑣 2
(speed 𝑣 in feet per second), determine the corresponding distance traveled by the orbiter. Assume
no braking from its wheel brakes.

Question 3 [P /034]: The cone falling with a speed 𝑣0 strikes and penetrates the block of packing
material. The acceleration of the cone after impact is 𝑎 = 𝑔 − 𝑐𝑦 2 , where 𝑐 is a positive constant and
𝑦 is the penetration distance. If the maximum penetration depth is observed to be 𝑦𝑚 , determine the
constant 𝑐.

Question 4 [P /037]: The stories of a tall building are uniformly 10 feet in height. A ball A is dropped
from the rooftop position shown. Determine the times required for it to pass the 10 feet of the first,
tenth, and one‐hundredth stories (counted from the top). Neglect aerodynamic drag.
