A hot-air balloon is rising upward with a constant speed of 2.14 m/s. When the balloon is 2.98 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?

A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away.  Find the time it takes for the ball to travel the horizontal distance to the plate.    2.5 s   0.40 s   4.6 s   0.22 s

A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?

A ball is rolled horizontally off a table with an initial speed of 0.24 m/s. A stopwatch measures the ball's trajectory time from table to the floor to be 0.30 s. How far away from the table does the ball land? (g = 9.8 m/s2 and air resistance is negligible).

A spacecraft has an initial speed of 3037 m/s at an angle of 27 degrees above the positive x axis. Two engines fire for 5.4 seconds, and produce an acceleration of 9.9 m/s/s at an angle of 18.5 degrees above the positive x axis. What is the final speed of the spacecraft? What angle is it at above the positive x-axis?

A lacrosse player is practicing against a wall. The ball leaves his stick 2.3 meters above the ground at a 33.5 degree angle from the horizontal with a speed of 9.3 m/s. The ball then hits the wall, 3.7 meters away. How high above the ground does the ball make contact with the wall?

A cannon is mounted on a tower above a wide, level field. The barrel of the cannon is 80 m above the ground below. A cannonball is fired horizontally with an initial speed of 800 m/s. Assuming air resistance can be neglected, approximately how long will the cannonball be in flight before it hits the ground? О 16 s 40 s 4 s 32 s 2 s About how far from the base of the tower will the cannonball land? 3000 m 800 m O 160 m 40 m 60000 m

A hot-air balloon is rising upward with a constant speed of 2.55 m/s. When the balloon is 2.91 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?

A rock is thrown from the ground towards a building with an angle of 65 degrees above the horizontal line and with an initial velocity of 30m/s. The horizontal distance between where rock was thrown and the building is 45 meters. Find the speed of the rock right before it hits the building.

A hot-air balloon is rising upward with a speed of 15.5 m/s at an angle of 32.8° with respect to the horizontal.  A rock is released from rest relative to the balloon when it is 938.9 m above the ground.  How much time elapses before the rock hits the ground?
