The Jurassic Park ride at Universal Studios theme park drops 25.6 m straight down essentially from rest. A. How much time does the drop takes ? B. What is the velocity at the bottom ?

3. A quarterback throws a football with initial velocity components Voy= 10.0 m/s (upward) and Vax = 19.0 m/s (down the field). It is caught at the same height it is thrown from. a. How long does it take for the football to reach its maximum height? b. How high is this point above where the ball was released? c. How much time, after it was thrown, elapses before the ball is caught? Compare this time to what you found in part (a). d. How far away from the quarterback is the ball when it is caught? 4. Repeat question 3, but have the initial speed of the ball be 28.0 m/s and the initial angle be 38.0° up from horizontal.

There is a freefalling object starting at rest.a.Exactly 1.8s later what will be its velocity?b.What is the displacement fallen after 1.8s later? C.If vertical and horizontal velocity components of a projectile are 127 m/s, what is the resultant velocity and direction?

After about 20 minutes, you begin to pick up velocity. You realize that you are headed toward a waterfall. Let’s hope it isn’t too high…. You reach the top of the waterfall traveling at 20 m/s. The waterfall is 1.6 m high. a. How long are you in the air?b. How far away from the base of the waterfall does your boat land?

A ball is thrown straight upward from a height of 3.2 m with a velocity of 13.0 m/s. a. What is the maximum height the ball reaches? b. How long does it take the ball to reach the maximum height? c. What is the total time the ball is in the air? d. With what velocity does the ball impact the surface?

A ball is dropped from an initial height of 25.0 m off of a cliff. A. Consider the following quantities (1) the speed of the ball (2) the velocity of the ball (3) the acceleration of the ball. Which of these is (are) zero when the ball is dropped? a. 2 only b. 1 and 3 c.1 only d. 1, 2, and 3 e. 1 and 2

A skydiverjumps out of a helicopter and falls freely for 13.3 s before opening the parachute.what is the skydivers speed in m/s when the parachute opens? B. How far below the helicopter in m is the skydiver 8.7 seconds after jumping from the plane?
