A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground.
The ball accelerates due to gravity. Using the equation y = 1/2??2 where y is the height, to compute g , calculate the acceleration of the ball.
A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground.
Since the value for g obtained from the data is inaccurate, one of the measurements must have been incorrect. Assuming the time was exactly accurate, from what height was the ball actually dropped?
You and your friend would like to experimentally determine a value for g, an object's acceleration due to gravity on Earth. Your friend sets a baseball on the edge of a desk, and you crouch down by the floor, waiting for the ball to drop. She pushes the ball off the desk and yells GO! to signal you to press START your phone's stopwatch app. When the ball hits the floor, you press STOP on the app to stop the timer, and see that the time reads t = 0.606 s. Using a tape measure with markings for cm, you measure the top of the desk to be h = 123 cm from the floor.
Part 1) Assuming the ball started with no initial vertical velocity, calculate the value of g in your experiment symbolically. Assume that g is a positive number.
Part 2) Using your previous symbolic answer and the qualities from the experiment, determine a numeric value for g.
Part 3) What is a reasonable quantitative estimate for your uncertainty in stopping the timer, sigma t? What about your error in measuring the height…

- 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.arrow_forwardA test rocket is fired vertically upward from a well. A catapult gives it initial speed 60 m/s at ground level. Its engines then fire and it accelerates upward at 5.0 m/s² until it reaches an altitude of 1,100 m. At that point its engines fail and the rocket goes into free-fall, with an acceleration of g=9.80 m/s². What is its velocity just before it collides with the Earth? (You will need to consider the motion while the engine is operating separately from the free-fall motion.) [Give your answer in m/s to the nearest 0.1 m/s]arrow_forwardThe NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.18 m above the floor. The ball hits the floor 0.147 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)?arrow_forward
- Consider a toy rocket that undergoes one dimensional motion. It is launched from rest straight up from the ground and rises under constant acceleration for Δt1 seconds, when it loses power. It hits the ground Δt2 seconds later. You can consider Δt1 = t1 – t0 and Δt2 = t2 – t1. What was the rocket’s acceleration before t1?arrow_forwardYou attach a meter stick to an oak tree, such that the top of the meter stick is 2.67 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.311 seconds to pass the length of the meter stick, how high (h0) above the ground in meters was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down?arrow_forwardMaria throws two stones from the top edge of a building with a speed of 12 m/s.

- A car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration? Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt. 0 m/s^2 27.91 m/s^2 13.96 m/s^2 9.84 m/s^2arrow_forwardPedro is driving a motorcycle along Espana boulevard.
