you drop a ball from a height of 2.00 m above the floor. The ball hits the floor 0.319 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     29.5 m/s^2     59.0 m/s^2     39.3 m/s^2     19.7 m/s^2

Figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On planet #2, you launch a projectile straight up from the ground at a speed of 27.9 m/s. The projectile reaches a maximum height of 75.5 m before falling back to the ground. What is the value of g for planet #2?

3. A ball is thrown upwards at 13.0 m/s toward the ceiling located 6 m above the point where you release the ball. Air resistance is negligible. Objects falling near the earth's surface with no forces acting except gravity have a downwards acceleration of magnitude g. For this problem use g = 10 m/s². Write any equation you use in symbolic form before substituting in numbers. Make a labeled picture with symbols and all relevant values. Put a coordinate system on the a. picture by indicating the location of the origin and position direction. b. Find the time taken to reach the ceiling. Find the velocity just before the ball touches the ceiling. C.

1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x =  ____m/s v0y =  ____m/s

The vertical displacement (in m) of a plane is  1.5 t2 up; t is the time (in s) after takeoff. The plane releases a package 2.0 s after takeoff. What is the magnitude of the velocity (in m/s) when the packaged is released? Report your answer in the appropriate number of significant digits. Answer value

We know that the moon Callisto revolves around Jupiter during a period of 17.0 days.17.0 days. The average distance from the center of Jupiter to the center of Callisto is 1.95×109 m.1.95×109 m. What is the acceleration ?a of Callisto due to its motion around Jupiter?

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.54 m above the floor. The ball hits the floor 0.392 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     10.0 m/s^2     15.0 m/s^2     30.0 m/s^2     20.0 m/s^2

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.40 m above the floor. The ball hits the floor 0.160 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     54.7 m/s^2     82.1 m/s^2     207.9 m/s^2     109.4 m/s^2

A thoughtful person on a bridge reflecting on his awesome Physics class sees a small stone by his feet. Hmm, he thought to himself. Using his foot he slowly nudged the stone off the surface of the bridge and using his cell phone he timed how long it took to hit the water, about 1.75 s. How high (m) is the bridge above the water? (neglect air resistance)

On the planet Koozebane, if a pebble is dropped from height h, it falls to the surface in time t. Data for the acceleration = 4.100 [m/s^2]; the height = 4.900 [m]. What is the time? Submit Answer Tries 0/12
