A spacecraft lands on a newly discovered planet orbiting the star 51 Pegasi. To measure the acceleration from gravity on the planet, an astronaut drops a rock from a height of 2 m. A precision timer indicates that it takes the rock 0.71 s to fall to the surface. What is the acceleration from gravity on this planet?
A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.
Each of the strobe photographs (a), (b), and (c) in Figure P2.13 was taken of a single disk moving toward the right, which we take as the positive direction. Within each photograph the time interval between images is constant. For each photograph, prepare graphs of x versus t, vx versus t, and ax versus t, vertically aligned with their time axes identical, to show the motion of the disk. You will not be able to place numbers other than zero on the axes, but show the correct shapes for the graph lines. Figure P2.13
Mr. And Mrs. Austria love to run around the town. From past experienced, they know that Mr. Austria can run 6km into time it takes Mrs. Austria 4km. They have decided that they need to run the same distance, 9km, and finish together. How much of a head start does Mrs. Austria need for them to finish together?
Caravan Analogy.Consider a highway that has tollbooths every 120 km. Suppose that cars travel at a rate of 120 km/hr (cars have instant acceleration to 120 km/hr and maintain that constant speed between tollbooths). If there is a convoy of 22 cars, and it takes each car an average of 24 seconds to clear the tollbooth, calculate the following. a. Suppose the caravan travels 360 km, beginning in front of one tollbooth, passing through a second and third tollbooth and finishing just after a fourth tollbooth. What is the end-to-end delay, in minutes, from the time the first car goes through tollbooth 1 until the last cargoes through tollbooth 4? b.The cast members of “The Fast and the Furious” show up. Instead of 22 cars, there arenow 18 cars. These 18 cars travel 220 km/hr instead of 120 km/hr. What is the new end-to-end delay in minutes? c. Consider the diagram below. The police are on to the cast of “The Fast and the Furious”. These 18 cars travel 280 km/hr on segments A and B (where…
2. Lucas and Greyson are running a race. Lucas starts the race 10 m closer to the finish line than Greyson. However, they reached the finish line in exactly the same amount of time! Which runner had the higher speed? Explain why.
Question from physics I want the solution as fast as possible???
Solve and answer the following question showing the complete step-by-step process. 1. The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub your toe in the dark, estimate the time it takes the nerve impulse to travel to your brain.
USE GRESA METHOD FOR THE SOLUTION 1. A 5.0 million-pound rocket takes off from rest in Houston, Texas. The rocket has attained 150 kph (kilometers per hour) of speed 8.00 s after the launch. Then, at the end of the first minute, its speed is 1,500 kph. (a) What is the average acceleration of the rocket, in m/s2, during the first 8.00 s? (b) What is the average acceleration of the rocket, in m/s2, between the first 8.00 s and the end of the first minute? (c) Suppose the acceleration is constant, but not necessarily the same, in both intervals stated in (a) and (b), how much distance has the rocket covered during the first 8.00 s, and (d) during the interval from 8.00 s to the end of the first minute?
Spaceman Spiff is stranded on an alien planet. In order to repair his spaceship, he needs to know what the acceleration due to gravity is on the planet. Spiff stands ona a cliff, throws a rock horizontally, and measures the time it takes to hit the ground 20m below. His data is shown in the following table. Calculate the acceleration due to gravity on this planet. Plot the velocity as a function of time. Can you show all the calculations please?
hi please solve this question , make sure its correct , please do it fast , i need just the answer i will rate
Classes are canceled due to snow, so you take advantage of the extra time to conduct some physics experiments. You fasten a large toy rocket to the back of a sled and take the modified sled to a large, flat, snowy field. You ignite the rocket and observe that the sled accelerates from rest in the forward direction at a rate of 13.5 m/s2 for a time period of 3.30 s. After this time period, the rocket engine abruptly shuts off, and the sled subsequently undergoes a constant backward acceleration due to friction of 6.15 m/s2. After the rocket turns off, how much time does it take for the sled to come to a stop? time: ? By the time the sled finally comes to a rest, how far has it traveled from its starting point? distance traveled: ?
