Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.27 m, and observe that it hits the floor 0.204 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 81.8 m/s^2 81.8 m/s^2 109.1 m/s^2 54.5 m/s^2
A spacecraft on its way to Mars has small rocket engines mounted on its hull; one on its left surface and one on its back surface. At a certain time, both engines turn on. The one on the left gives the spacecraft an acceleration component in the x direction of ax = 5.10 m/s², while the one on the back gives an acceleration component in the y direction of a = 7.30 m/s2. The engines turn off after firing for 670 s, at which point the spacecraft has velocity components of vx = 3515 m/s and vy = 4136 m/s. What was the magnitude and the direction of the spacecraft's initial velocity before the engines were turned on? Express the magnitude as m/s and the direction as an angle measured counterclockwise from the +x axis. magnitude direction m/s º counterclockwise from the +x-axis
You are on the roof of a Physics Building, 51 m above the ground. Your physics professor, who is 1.84 m tall, is approaching the building at constant speed of 1.19 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg? Do not round the answer. Put all the decimals.
A worker at the top of a 390-m-tall television transmitting tower in North Dakota accidentally drops a heavy tool. If air resistance is negligible, how fast (in m/s) is the tool going just before it hits the ground?
You are on the roof of a Physics Building, 41 m above the ground. Your physics professor, who is 1.65 m tall, is approaching the building at constant speed of 2.09 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg?
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. After the rocket's engine turns off at a height of h=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground? Ignore air resistance.
While standing on the roof of a building, a boy throws a tennis ball with an initial speed of 15 m / s at an angle of 35 ° below the horizontal. The ball lands on the ground 2.8 s later. How tall, in meters, is the building?
An astronaut exploring a distant solar system lands on a planet with a gravitational acceleration of 746 m/s. What is the maximum height an astronaut could reach when jumping straight up starting with an initial speed of 1.80 m/s?
You are on the roof of a Physics Building, 19 m above the ground. Your physics professor, who is 1.78 m tall, is approaching the building at constant speed of 1.57 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg?
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
You are on the roof of a Physics Building, 51 m above the ground. Your physics professor, who is 1.61 m tall, is approaching the building at constant speed of 2.35 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg?
You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
