On the same sets of axes, using a page of graph paper: plot by hand the vertical velocity vy vs. t (y=mx+b), for
(a) a ball thrown upwards at 12.0 m/s and
(b) a ball that is dropped, and
(c) a ball thrown downwards at 12 m/s. Use g=9.80 m/s/s and a time range from 0 to 2.0 s.
Use the convention that “+” means “upwards” and viceversa.
Which has the longest time-of-flight?
Which has the lowest impact speed when it hits the ground?

A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....

Answer: 10.12 A key is dropped from a bridge that is 40.0 m bove the water. At the moment the key is released a model boat is 10.5 m away from the bridge and moving towards the bridge with constant velocity. If the key falls directly into the model boat, calculate the Velocity of the boat. Answer: 11. [2pt] Arie is aimed honuntaily a target located 345 m away.
