Question 6 The next few questions challenge you to figure out the acceleration due to gravity ( g) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 68.4 m above the ground, and the stone hits the ground 5.49 s later. What is the value of g on Planet #1? 1 24.92 m/s^2 2) 4.54 m/s^2 3. 2.27 m/s^2 4. 12.46 m/s^2 --/5 Question 7 funm the ground at a speed of 51.2 m/s. The projectile reaches a

5. An astronaut drops a hammer from 2.0 meters above the surface of the Moon. If the acceleration due to gravity on the Moon is 1.62 meters per second, how long will it take for the hammer to fall to the Moon's surface? (1) 0.62 s (2) 1.2 s (3) 1.6 s (4) 2.5 s S (1

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.

The trap-jaw ant, found throughout tropical South America, catches its prey by very rapidly closing its mandibles around  its victim. Shown is the speed of one of its mandible jaws versus time in microseconds. a. What is the maximum acceleration of the ant’s mandible? b. The mass of a trap-jaw ant’s mandible has been estimated to be about 1.3 x 10-7 kg. Estimate the maximum force exerted by one mandible.

1.A spacecraft starts from rest, and makes a journey to a destination 258000 km from its starting point. It does so by accelerating at a constant rate of 11.65 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 11.65 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?     2 hr 37 min     1 hr 51 min     6 hr 9 min     3 hr 5 min   2. An unidentified flying object (UFO) is observed to travel a total distance of 47000 m, starting and ending at rest, over a duration of 1.18 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.     6,882 g s     135,019 g s     67,509 g s     13,763 g s   3. A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The…

What is the velocity of the object at the indicated point? O 0 = v(- cos(0)î + sin(0)ĵ) O i = v(- sin(@)î + cos(8)ĵ) O ū = v(- sin(0)î – cos(0)ĵ) ü = v(sin(0)î + cos(0)Î) O i = v(cos(0)î + sin(0)ĵ)

You start out by driving 82 miles north in 4 hours and 36 minutes, and then you stop and park for a while. Finally you drive another 60 miles south in 3 hours and 11 minutes. The average velocity for your entire trip was 2.26 miles per hour to the north. How much time did you spend parked?1 hour 56 minutes  3 hours 53 minutes  0 hours 58 minutes  9 hours 43 minu

**30. The gravitational acceleration on the surface of the moon is 1/6 what it is on earth. If a man could jump straight up 0.7 m (about 2 feet) on the earth, how high could he jump on the moon?

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?
