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 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 63.0 cm and the recorded time was 311 ms (millisecond). Calculate the magnitude of the velocity at the lower photogate

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).

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...

In an experiment to measure the acceleration due to gravity g, two independent equally reliable measurements gave 9.67 m/s2 and 9.88 m/s2. Determine (i) the percent difference of the measurements (ii) the percent error of their mean [Take the theoretical value of g to be 9.81 m/s]

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...

1) Why is there a different equation for elastic vs inelastic collisions? Are they really different? 5) If the first car does not go through either photogate after collision, what will its velocity essentially be? The conservation of momentum is a fundamental law in classical mechanics. It states that the total momentum of a system at the initial condition and ending conditions must be equivalent or p. - P. This can be modeled by studying the effect of objects in...

Two students are discussing what determines the direction of an object’s velocity change arrow. Student A says: The velocity change arrow is in the same direction as the velocity of the object. Student B says: The velocity change arrow is independent of the velocity of the object. You have the following equipment: spring scale, mass, stand, motion sensor, stopwatch, metre stick What kind of experiment to do to prove one of the student is wrong? My answer: I believe student...
