the resultant velocity

what’s the initial and final height of the ball?

You are on the ferry from Seattle to Bremerton. As you stand on the rear outside deckwatching the receding Seattle skyline, the ferry travels at a constant velocity. Whileleaning over the rail, you accidentally drop an apple. Neglect air resistance. Describethe path of the falling apple as seen by:a. Youb. A seal relaxing on a nearby anchored (stationary) boat.Explain your answer for both parts.

When baseball players throw the ball from the out eld, they usually allow it to take one bounce before it reaches the in eld because they think that the ball will arrive sooner that way. Suppose that the angle at which a bounced ball leaves the ground is the same as the angle at which it is thrown but the ball's speed after the bounce is one-half of what it was just before the bounce. (a) Assume that the ball is always thrown with the same initial speed. At what angle  should the elder throw the ball to make it go the same distance D with one bounce as a ball thrown upwards at 45  with no bounce? (b) Determine the ratio of the time intervals for the two paths. Is it better to throw the ball on a bounce?

If you double the initial speed of a projectile, what happens to that projectiles range? Assume that the projectile lands at the same height from which it was launched

why is the projectile motion in 2 directions can be studied as a combination of 2 one directions?

a roller coaster begins its movement from an initial height of 25 m in the air and an initial velocity of 0 m/s. Later in the movement, the roller coaster is moving at 12 m/s. Calculate the height of the roller coaster at this point, assuming the roller coaster and track are an isolated system.

What is the intial velocity in the y direction of a projectile?

An 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. 0 O 0 (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 45.0° with no bounce (green path)? (b) Determine the ratio of the time interval for the one-bounce throw to the flight time for the no-bounce throw. tone-bounce tno-bounce

If a rocket is shot and lands 200m away, how long was it in the air if the initial velocity was 33 m/s and the angle is 75?
