To find the acceleration of a glider moving down a sloping air track, you measure its velocity at two points (?1 and ?2) and the time it takes between them: ?1 = 0.21 ± 0.05 ?/? ?2 = 0.85 ± 0.05 ?/2 ? = 8.0 ± 0.1 ?
a. Assuming all uncertainties are independent and random, and acceleration is calculated using ? = ?2−?1 ? , what should you report for ? and its uncertainty?
b. You calculate using an air resistance model that the acceleration should be 0.13 ± 0.01 ?/? 2 . Does your measurement agree with this prediction?

To find the acceleration of a glider moving down a sloping air track, you measure its velocities (V1 and V2) at two points and the time t it takes between them, as follows: V1=0.21+/- 0.05m/s, V2=0.85 +/- 0.05m/s, t=8.0 +/- 0.1s a) Assuming all uncertainties are independent and random, find the average acceleration, a=(v2-v1)/t , and its uncertainty. b) How well does your result in part (a) agree with your friends theoretical prediction that a=0.13 +/- 0.01m/s^2

I need help for numbers 1 and 3. For number one I
measured the height of the track at angle. One of the heights was
.082m. hypotenuse 1.013m. I did sin^-1(.082/1.013) and got 4.64
degrees. I used a sensor and aquired data for change in v and t as
a glider fell down the track. I calculated the acceleration at that
height and angle as -10.18 m/s^2. final V was 1.48, initial V .687.
final t=.0675, initial t= .1454.
