Physics 101 Mechanics

ou are designing a high-speed elevator for a new skyscraper. The
elevator will have a mass limit of 2400 kg (including passengers).
For passenger comfort, you choose the maximum ascent speed to be
18.0 m/s, the maximum descent speed to be 10.0 m/s, and the maximum
acceleration magnitude to be 5.10 m/s2. Ignore friction.
What is the minimum time it will take the elevator to ascend
from the lobby to the observation deck, a vertical displacement of
640 m?
What is the maximum value of a 60.0-kg
passenger’s apparent weight during the ascent?
What is the minimum value of a 60.0-kg passenger’s
apparent weight during the ascent?
What is the minimum time it will take the elevator to descend to
the lobby from the observation deck, a vertical displacement
of 640 m?

Two strings, each 14.2 m long, are stretched side-by-side. One string has a mass of 78.0 g and a tension of 247.0 N. The second string has a mass of 58.0 g and a tension of 194.0 N. A pulse is generated at one end of each string simultaneously. Once the faster pulse reaches the far end of its string, after what additional time interval will the slower pulse reach the end of its string?

Review Concept Simulation 9.2 and Conceptual Example 7 as
background material for this problem. A jet transport has a weight
of 2.16 x 106 N and is at rest on the runway. The two rear wheels
are 16.0 m behind the front wheel, and the plane's center of
gravity is 11.6 m behind the front wheel. Determine the normal
force exerted by the ground on (a) the front wheel and on (b) each
of the two rear wheels.

For a 1.00 m-long ballistic pendulum that consists of a 10 g bullet and an 890 g catcher, what is the speed (m/s) of the combined bullet-catcher right after the collision, given a maximum deflection angle of 10.18 degrees? [Hint: make sure your calculator is in degree mode]

A 11.0 g bullet strikes a 9.90 kg, 1.00 m wide
door at the edge opposite the hinge. The bullet embeds itself in
the door, causing the door to swing open with angular velocity of
2.00 rad.s-1. What was the speed of the bullet just
before impacting the door?
m.s-1 (3 sf)

Eventually, poor AJ loses his grip and begins to roll off HAWAC and then continues to roll (without slipping!) down a series of hills across campus toward the Fox River. How far down will AJ descend vertically before he reaches a speed of 580 rotations per minute? (Treat AJ like a solid sphere of diameter 58 cm. I = 2/5 * mr^2. Remember his mass is 20 kg and assume his fall started from rest.)
