A student developed an experiment to measure the acceleration of the gravity. In the experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The distance between the two photogates was 50 cm and the recorded time was 319 ms (millisecond). Calculate the acceleration of gravity (magnitude).

Answer #1

using 2nd equation of motion

h = 0.5 gt^2

0.5 = 0.5 g* 0.319^2

g = 9.8269 m/s^2

    A student developed an experiment to measure the acceleration of the gravity. In the experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The distance between the two photogates was 48 cm and the recorded time was 316 ms (millisecond). Calculate the magnitude of the velocity at the lower photogate.

    A student developed an experiment to measure the gravitational acceleration. In this experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The student recorded time (t) and the distance (y) between the two photogates as shown in the following table: t (s) y(m) 0.141 0.100 0.199 0.200 0.244 0.300 0.281 0.400 0.315 0.500 0.345 0.600 0.372 0.700 Use Excel to plot y versus...

    In an experiment where you try to measure the acceleration due to gravity (g) by dropping an object from a certain distance into a sensor pad that measures the time of fall, what would be some of the experimental errors? I know that inaccurately measuring the height of the fall is one of them, but what would be other types of errors? The equation needed to calculate g is 2h/t^2.

    One way to measure g on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 4.00 s for a ball to fall freely 11.54 m , starting from rest. A-What is the acceleration due to gravity on that planet? Express your answer in m/s2. B-What is the acceleration due to gravity on that planet? Express...

    C.A student performs the experiment and measures the distance between photogates d=50 +/- 0.1 cm, the times measured by photogates: t1=0.052 +/- 0.001s and t2=0.035 +/- 0.001s and the carts length s=10 +/- 0.5cm. Find the acceleration a of the cart and estimate the uncertaintainy in a. D. The student repeats the measurements and obarins more values of the accerelation: 5.15 m/s^2, 4.22 m/s^2, 4.63m/s^2, 3.92m/s^2, 4.58m/s^2, 4.27m/s^2.

    6. Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration greater than 1000 ms lasting for at least 1 ms will cause traumatic injury. Suppose a small child rolls off a bed that is 0.42 m above the floor. Assume the child remains horizontal during the fall to the floor. If the floor is hardwood, the child's head is brought to rest in a distance of approximately 2.0 mm Note that...

    Note: Show this using kinematic equations, please. The acceleration due to gravity g near the surface of the Earth can be measured by projecting an object vertically upward and measuring the time that it takes to pass two given points in both directions. See the diagram below. Notice that the horizontal axis is time not position the path of the object is purely along a straight, vertical line. Show that if the time the body takes to pass a horizontal...
