THIS time, though, there is a window in the floor, and you can see that you re in a rocket which 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 7.44 m/s^2. When you drop a ball from a height of 2.20 m, it hits the floor 0.358 s later. What is the value of g for the alien world below you? 35.5 m/s^2 53.8 m/s^2 26.9 m/s^2 44.1 m/s^2

On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 21.5 m above the ground, with an initial speed of 40.1 m/s. The projectile lands 36.9 m away from the base of the cliff. What is the value of g for planet #3?     21.22 m/s^2     50.78 m/s^2     25.39 m/s^2     128.36 m/s^2

A ball is released from rest from the top of the empire state building. Use g=9.8 m/sec^2 and ignore air resistance. What is the speed of the ball 1 second after it is released? 3 seconds?

You are on your way to the store but realized you forgot your car keys. You ask your friend to throw you the keys from the apartment complex.  The window your friend throws it from is 10 meters above the ground, and he chucks them with a speed of 2m/s at an angle of 25 degrees above horizontal.  Acceleration due to gravity near the surface of earth is 9.8m/s^2 1) How far from the window do you need to stand to catch the keys.

You are working part-time for the GT Sports Media Complex, editing video for the women’s softball team. In one particular clip, a GT player hits a home run over the center field fence. The ball leaves the bat at a height of 4 ft, and crosses the outfield fence (220 ft away) at a height of 10 ft. Logs of the game indicate that the pitch was clocked at 68 mph as it reached the plate. Your frame-by-frame analysis of the 30-frame-per-second video indicate that the ball spent only a single frame in contact with tha bat, and another 126 frames travelling to the outfield fence. A quick internet seach tells you that a typical college softball weighs 0.4 lb. How many pounds of average force act on the ball during ocntact with the bat?

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?

On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 76.0 m above the ground, with an initial speed of 31.2 m/s. The projectile lands 71.5 m away from the base of the cliff. What is the value of g for planet #3?     848.50 m/s^2     28.94 m/s^2     14.47 m/s^2     12.05 m/s^2

The Hulk, on the 75th story of Stark Tower (225 m off the ground), sees Tony drop his penny. He catches the penny and throws it back to Tony. What is the minimum speed necessary for Hulk's throw in order for the penny to reach Tony? (Note: nobody bothers trying to get Mjolnir back to Thor. He's on his own.)

suzie is standing at the top of a cliff.  she says if she drops a heavy rock off the cliff it is 110 meters high. the rock starts from rest, and gravity accelerates the rock at 9.81 m/s^2 downwars.   how long it should take for the rock to fall 110meters?

OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which 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 7.42 m/s^2. When you drop a ball from a height of 1.74 m, it hits the floor 0.254 s later. What is the value of g for the alien world below you? 1. 63.8 m/s^2 55.2 m/s^2 3 79.1 m/s^2 4 46.5 m/s^2
