Jessup can throw a ball a maximum distance (measured horizontally from the point of release) of D. (a) To what maximum distance can he toss the same ball (vertically) upwards? (b) In which situation does the ball spend more time in the air? How much longer is this (express your answers multiples of the shorter time) than the other time?

Answer #1

a) The range of projectile motion is maximum when the angle of projectile motion is 45 dergees

Let the initial velocity be v. Then

OR

Suppose the ball is thrown upwards with the initial velocity v. Then the height reached by the ball is

Therefore the maximum distance at which he toss the same ball (vertically) upwards is h = D/2

b) Time spent in air when the ball is thrown as projectile motion is

Time spent in air when the ball in thrown vertically upwards is

which is greater than the time spent in air when the ball is thrown as projectile motion

Therefore

(1 point) A ping-pong ball is caught in a vertical plexiglass column in which the air flow alternates sinusoidally with a period of 60 seconds. The air flow starts with a maximum upward flow at the rate of 4.4m/s and at t=30 seconds the flow has a minimum (upward) flow of rate of −7.8m/s. (To make this clear: a flow of −5m/s upward is the same as a flow downward of 5m/s. The ping-pong ball is subjected to the forces...

A muon is a type of unstable subatomic particle. When high-speed particles from outer space (sometimes called "cosmic rays") collide with atoms in the upper atmosphere, they can create muons which travel toward the Earth. Suppose a muon created in the atmosphere travels at a speed of 0.941c toward the Earth's surface for a distance of 3.48 km, as measured by a stationary observer on Earth, before decaying into other particles. (a) As measured by the stationary observer on Earth,...
