OK, yet another strange awakening in a room with no windows. This time you drop a ball from a height of 2.50 m and it hits the floor 0.500 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? 20.0 m/s^2 19.4 m/s^2 10.2 m/s^2 29.8 m/s^2

A ball is suspended from a light 1.3 m string . The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)?  What will be the maximum angle, in degrees, the string will make with the vertical?

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?

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
