What are the components of the velocity of the baseball just before it lands on the ground? e) What is the final magnitude and direction of the baseball? d)

If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, then compare their impact velocities.  a)The impact velocity when throwing a stone above horizontal will be more than the case when throwing a stone below horizontal. b The impact velocities of the two situations will be the same.  c More information is needed to conclude the relative strength of impact velocities. d).The impact velocity when throwing a stone above horizontal will be less than the case when throwing a stone below horizontal.  which option is correct

1. The distance between home plate and the pitcher's mound in baseball is 60.5 ft. In MLB, baseballs are. pitched at about 90mph. Assume the ball is thrown perfectly horizontally, at 0°. How far in feet will the ball drop during its transit to home plate? Use g = 32 ft/s². (Note: this is why pitcher's mounds are raised.) 2. A pebble is tossed into the air at an angle of 62° above the horizontal, with an initial speed of 4.8 m/s. The pebble is 1.6m above the ground when it is released by the thrower's hand. a) How long will the pebble remain airborne? b) What maximum height above the ground will the pebble achieve?

This is a practice hw question not graded!!

A baseball player hits a ball 1.1m above the plate at an angle of 42 degrees at a speed of 35 m/s. In order to hit a home run, the ball has to clear a 2.4 m tall wall, 120 m away from the plate.  a) sketch the situation, including a coordinate system and the ball's trajectory.  b)how many seconds is the ball in the air, which it reaches the wall?  c) does the ball go over the wall for a home run? (find its vertical position at the appropriate time)  d) what is the ball's speed and direction, as it reaches the wall?

A fire hose ejects a stream of water at an angle of 36.1° above the horizontal. The water leaves the nozzle with a speed of 24.0 m/s. Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire? Number i Units +
