What is the difference between speed and velocity?

An object falls from a high building.  What will its velocity be after 7 seconds of falling?  An object falls from a high building and hits the ground in 9.5 seconds.  What is the height of the building? During a storm, a piece of metal was knocked off a building.  The metal fell a distance of 300 meters to the ground. How long did it take the metal to hit the ground? What will the velocity of the metal be when it hits the ground? An object falls from the Burj Khalifa (located in United Arab Emirates) and takes 13 seconds to hit the ground.     What is its velocity at impact?   How tall is the building? What is the object’s acceleration at the 3rd second? What is the object’s acceleration at the 7th second? If the Burj Khalifa were actually 2000 meters tall, how long would an object take to fall from the top of the building to the ground? A cartoon coyote (who is it?) drops an anvil off a cliff to try to catch a bird (who is it?).…

really need asap

A bullet is fired straight upward with a speed greater than 200 m/s. What will be its speed (in m/s) three seconds before reaching maximum height?

What is the acceleration at 8.2 s?

How long does it take for an object thrown straight up in the air with the velocity a 50 M/S to reach the peak of its path?

A rock is dropped from a height of 50 meters above the ground.What was the magnitude of the velocity of the rock right before it hit the ground?

A) If a ball moving at 5m/s receives constant acceleration of 1m/s2 at the same direction, how long will it take the ball to reach 10m/s? 1 s 3 s 5 s 7 s B) If a ball's horizontal initial velocity is 20m/s and the flight time is 5 seconds, what is the ball's horizontal distance? 4 m 20 m 50 m 100 m
