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).

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...

Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration less than 800 m/s2 lasting for any length of time will not cause injury, whereas an acceleration greater than 1000 m/s2 lasting for at least 1 ms will cause injury. Suppose a small child rolls off a bed that is 0.41 m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 1.8 mm. If...

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...
