OK, yet another strange awakening in a room with no windows. This time you drop a ball from a height of 1.83 m and it hits the floor 0.428 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be?   A 10.2 m/s^2   B 29.8 m/s^2   C 20.0 m/s^2   D 16.3 m/s^2

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

5. You wake up in a strange room, with opaque walls, and no visible doors or windows. though there is a window on the floor, and you can see that you're in a rocket that has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 5.31 m/s^2. When you drop a ball from a height of 2.27 m, it hits the floor 0.290 s later. What is the value of g for the alien world below you?     48.7 m/s^2     63.8 m/s^2     56.3 m/s^2     82.8 m/s^2

A hot air balloon flying horizontally at a velocity of 50m/s and at an altitude of 475 meters when one if its sandbags falls off.  A. How long (in seconds) does it take the sand bags to reach the ground? B. What horizontal distance (in meters) will the bag travel before it strikes the ground?

An astronaut lands on a newly discovered planet (that has a nice gravitational constant). He proceeds to jump out of the spacecraft and onto the planet's surface. His height above the ground (in feet) after t seconds is given by the function h (t) =-3t2 +12t +36. A. How high off the ground is the astronaut after 1 second? B. What is the astronaut's velocity after 1 second? Is he traveling up or down? C. How fast is the astronaut traveling when he lands on the planet? D. When will the astronaut be at his highest point in the jump? E. Is the astronaut speeding up or slowing down after 2 seconds? At what rate?

24. A rocket is fired upward on a straight upward trajectory at 90 degrees to the surface perfectly, starting from rest with an acceleration of +29.4 m/s² for the first 4 seconds of travel. After finishing these 4 seconds it runs out of gas but continues its upward movement on its original path for a short time. a. b. What is the maximum height it reaches? If after reaching the maximum height it is allowed to fall in free fall in a perfectly linear path towards the earth, what is its final speed just before hitting the ground? Select one: - b. a. Maximum height = 135.8 meters, final velocity = 940.8 meters/seconds Maximum height = 940.8 centimeters, final velocity = 135.8 centimeters/seconds c. Maximum height = 940.8 centimeters, final velocity = 13.58 meters/seconds d. Maximum height = 940.8 meters, final velocity = 135.8 meters/seconds

A particle moves according to a law of motion s = 2t^3 − 9t^2 + 12t + 1.a. Determine the velocity of the particle when it has acceleration of 2 m/s^2.b. When is the particle moving in a positive direction?

Asap plzzzz

This time you drop a ball from a height of 1.82 m and it hits the floor 0.365 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be?     27.3 m/s^2     33.3 m/s^2     17.5 m/s^2     37.1 m/s^2
