- You wake up in a strange room. There is a window on the floor, and you can see that you are 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 7.03 m/s^2. When you drop a ball from a height of 2.15 m, it hits the floor 0.384 s later. What is the value of g for the alien world below you? 22.1 m/s^2 39.0 m/s^2 30.6 m/s^2 33.2 m/s^2arrow_forwardOK, 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 8.07 m/s^2. When you drop a ball from a height of 1.46 m, it hits the floor 0.245 s later. What is the value of g for the alien world below you?arrow_forwardA javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70 cm as she throws. She releases the javelin 2.0 m above the ground traveling at an angle of 30 ∘ above the horizontal. Top-rated javelin throwers do throw at about a 30 ∘ angle, not the 45 ∘ you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30 ∘ than they would be able to at 45 ∘ . In this throw, the javelin hits the ground 72 m away. What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration. Express your answer to two significant figures and include the appropriate units.arrow_forward
- You are lucky enough to visit a particular location in the universe that has zero gravity and no air resistance, so you decide to perform a simple experiment by throwing a rock horizontally. What type of motion do you observe?arrow_forwardYou are on a space station, in a circular orbit h = 500 km above the surface of the Earth. You complete your tasks several days early and must wait for the next mission from the surface to bring you home. After days of boredom, you decide to play some golf. Walking on the space station surface with magnetic shoes, you tee up a golf ball. You hit it with all of your might, sending it off with speed υrel, relative to the space station, in a direction parallel to the velocity vector of the space station at the moment the ball is hit. You notice that you then orbit the Earth exactly n = 2.00 times and you reach up and catch the golf ball as it returns to the space station. With what speed υrel was the golf ball hit?arrow_forwardOK, 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 6.64 m/s^2. When drop a ball from a height of 1.57 m, it hits the floor 0.236 s later. What is the value ofg for the alien world below you you? 1 58.0 m/s^2 94.4 m/s^2 3 49.7 m/s^2 4 66.2 m/s^2 2.arrow_forward
- We track the particle’s trajectory between t = 0 to t = T. During this interval, how much time transpires in the particle’s non-inertial reference frame?arrow_forwardYou can see that you are in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out the window you determine that the rocket is accelerating upward at 8.26 m/s^2. When you drop a ball from a height of 1.81 m, it hits the floor 0.275 s later. What is the value of g for the alien world below you? 48.7 m/s^2 59.4 m/s^2 39.6 m/s^2 57.7 m/s^2arrow_forward8. solve the IVP differential equation for v then do b if you can/wantarrow_forward
- A physics student stands on a cliff overlooking a lake and decides to throw a softball to her friends in the water below. She throws the softball with a velocity of 22.5 m/s22.5 m/s at an angle of 39.5∘39.5∘ above the horizontal. When the softball leaves her hand, it is 15.5 m15.5 m above the water. How far does the softball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer.arrow_forwardThree astronauts leave Cape Canaveral, fly to Mars and back, and then splash down in the Pacific Ocean. An Admiral bids them goodbye at the Cape and then sails to the Pacific Ocean in an aircraft carrier where he picks them up. Who has the greater displacement, the admiral, or the astronauts?arrow_forwardOK, 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 8.00 m/s^2. When you drop a ball from a height of 2.41 m, it hits the floor 0.209 s later. What is the value of g for the alien world below you? a. 111.3 m/s^2 b. 153.5 m/s^2 c. 102.3 m/s^2 d. 120.2 m/s^2arrow_forward
