Billy-Joe stands on the Brooklyn Bridge kicking stones into the water below. If Billy-Joe kicks a stone with a horizontal velocity of 3.50 m/s, and it lands in the water a horizontal distance of 5.40 m from where Billy-Joe is standing, what is the height of the bridge
A marble is fired horizontally from a 3.0m high shelf using a toy gun so that its launch velocity is 2.0m/s. You will use a y axis that points down for this problem since the projectile will not rise above the level of the shelf at all.
a)using the equation Δx=(1/2)gt2 find how long it takes until this projectile hits the ground
b) using the eqn x = vot for the horizontal part of the flight of this projectile determine how far from the base of the shelf the marble lands
c) find the landing speed by using energy conservation (hint: let the mass of the marble be m)
(2) What analysis model correctly describes the motion of the ball in the vertical direction as observed by the professor?

- Prove that the trajectory of a projectile is parabolic, having the form y=ax+bx2. To obtain this expression, solve the equation x=v0xt for t and substitute it into the expression for y=v0yt(1/2)gt2 (These equations describe the x and y positions of a projectile that starts at the origin.) You should obtain an equation of the form y=ax+bx2 where a and b are constants.arrow_forwardQ5) A boy tosses a ball onto the roof of a house.

The cannon’s angle is 45.0° and the velocity is 21.0 m/s. The manager needs to know where to place the hoop and safety net.a) How far from the cannon should the safety net be placed?b) What is the time required to reach the height of the hoop?c) How far from the cannon should the hoop be placed?d) Sketch the setup of the stunt showing the location of the cannon, hoop and net?arrow_forward22arrow_forwardAn outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in the figure, but that the ball's speed after the bounce is one-half of what it was before the bounce. D (a) Assuming the ball is always thrown with the same initial speed, at what angle should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 40.0° with no bounce (green path)?
