A Projectile is launched from the top of a building with an initial velocity of 30m/s at angle of 60° above the horizontal. The magnitude of its velocity at t= 5 s after the launch is

A cruise ship moves southward in still water at a speed of 20.0 km/h, while a passenger on the deck of the ship walks toward the east at a speed of 5.0 km/h .The passengers velocity with respect to Earth is?

MULTIPLE -CHOICE QUESTION A baseball is launched from the bat at an angle θo = 30° what respect to the positive x-axis and with an initial speed of 40 m/s ,and it is caught at the same height from which it is was hit. Assuming ideal projectile motion (pos...

A ball is thrown straight up by a passenger in a train that is moving what a constant velocity. Where would the ball land —back in his hands, in front of him, or behind him? Does your answer change if the train is accelerating in the forward direction? if...

Two cannonballs are shot in sequence from a can-non, into the air, with the same muzzle velocity, at the same launch angle. Based on their trajectory and range, how can you tell which one is made of leand and which one is made of wood. If the same cannonb...

A rocket-powered hockey puck is moving on a (friction-less) horizontal air-hockey table. The x- and y-components of its velocity as a function of time are presented in the graphs below. Assuming that at t=0 the puck is at (X0,Y0)=(1,2), draw a detailed gr...

In a projectile motion, the horizontal range and the maximum height attained by the projectile are equal . A) what is the launch angle? B) If everything else slays the same , how should the launch angle, ¦È0, of a projectile be changed for the range of th...
