Problem 5: Near the surface of the Moon the acceleration due to gravity is roughly 1.67 m/s2 towards the lunar surface. The weapons platform begins to free-fall from 2 km up towards the surface initially with a velocity of O with all the members of the Presidential Time Squad onboard. A: What would be the velocity of the platform when it contacts the lunar surface? B: If James Monroe can re-activate the thrusters, they can provide an upwards acceleration of...
Free Fall On the moon, the acceleration due to gravity is 1.6 m/sec2.(a) If a rock is dropped into a crevasse, how fast will it be going just before it hits bottom 30 sec later?(b) How far below the point of release is the bottom of the crevasse?(c) If instead of being released from rest, the rock is thrown into the crevasse from the same point with a downward velocity of 4 m/sec, when will it hit the bottom and...
is ball on Moon, where the acceleration due to gravity is 1/6(g -9.8) and air resistance is negligible, is hit directly upward and returns to the same level 85 s later, (a) How high above its origjinal point did the ball go? (b) How fast it moving just a after it was hit? 7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00...
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
2. Artificial gravity is necessary for humans to stay healthy during extended stays in space. To provide artificial gravity, a space station is shaped like a cylinder with a diameter of 2200 m, and it rotates about its center at a constant rate. The astronauts live inside the cylinder at the outer edge, and feel a gravitational pull outwards. (a) How long should one revolution of the space station take if the acceleration of an astronaut on the outer edge...
1). Near the earth surface, acceleration due to gravity is 9.8 m/s a) True b) False c) Can's say 2). The force exerted normal to the surface is called "normal force" a) False b) True c) Statement is wrong 3). The normal force Fn acting on a horizontally place object of mass 10 kg is (assume at rest) a) 98 N b) 90 N c) 49 N d) 50 N 4). An object of mass 'm' is accelerated vertically upward...
is attached to a string and rotated in a vertical circle of radius 04 m with constant speed of 12 m/s. Calculate the tension of the bottom of the circle. string at the top and the (b) Moon is revolving around the earth once every 28 days. Determine its angular speed in rad/s. O If the distance between earth and the moon is 3.8 x 10 m, determine the mass of the earth. 6. A 0.2 kg ball is sliding...
What are the Solutions to Part B of Chapter 2 of Tillery Physics 9th edition.......kinda pointless for you guys to only have the solutions that the book has already. 1. What was the average speed in km/h of a car that travels 400.0 km in 4.5 h? 2. What was the average speed in km/h of a boat that moves 15.0 km across a lake in 45 min? 3. How much would a 80.0 kg person weigh (a) on Mars,...
