Question

When you fly in an airplane at night in smooth air, you have no sensation of motion, even though
the plane may be moving at 800 km/h (500 mi/h). Why?

1. You throw a ball vertically upward from the roof of a tall building. The ball leaves your hand at a
point even with the roof railing with an upward speed of 15.0 m/s; the ball is then in free fall. On its
way back down, it just misses the railing. Find (a) the ball's position and velocity 1.00 s and 4.00 s
after leaving your hand; (b) the ball's velocity when it is 5.00 m above the railing; (c) the maximum
height reached; (d) the ball's acceleration when it is at its maximum height.
2. An antelope moving with constant acceleration covers the distance between two points 70.0 m
apart in 6.00 s. Its speed as it passes the second point is 15.0 m/s. What are (a) its speed at the first
point and (b) its acceleration?
3. (a) If a flea can jump straight up to a height of 0.440 m, what is its initial speed as it leaves the
ground? (b) How long is it in the air?
4. A projectile is fired upward at an angle e above the horizontal with an initial speed Vo. At its
maximum height, what are its velocity vector, its speed, and its acceleration vector?
5. Sketch the six graphs of the x- and y-components of position, velocity, and acceleration versus time
for projectile motion with x0 = y0 = 0 and 0 < a< 90°
6. An important piece of landing equipment must be thrown to a ship, which is moving at 45.0 cm/s,
before the ship can dock. This equipment is thrown at 15.0 m/s at 60.0° above the horizontal from
the top of a tower at the edge of the water, 8.75 m above the ship's deck. For this equipment to
land at the front of the ship, at what distance D from the dock should the ship be when the
equipment is thrown? Ignore air resistance.

8. Why is the earth only approximately an inertial reference frame?
9. Can a body be in equilibrium when only one force acts on it? Explain.
10. A spaceship far from all other objects uses its thrusters to attain a speed of 1x104 m/s. The crew
then shuts off the power. According to Newton's first law, what will happen to the motion of the
spaceship from then on?
