please help me in these two questions
6) The maximum average time for a cart to travel through photogates is, At E 0.8 s, while the max minimum average time for the same measurement is At 0.7 s What is the uncertainty for main average time? 7) When a car travels through a photogate, you measure it's speed to be 2.6 After the car travels an additional 85 cm, it passes through a second photogate and its speed is measured to be 2.5 m. What is the magnitude of the average acceleration between these two measurements? (Be careful with the mixed units).Explanation / Answer
6.)
uncertainity = deviation/Actual vaue
= 0.1/0.7 = 0.142
= 14.2%
7.)
using eqn of motion
V^2 = U^2 + 2as
2.6 ^2 = 2.5^2 + 2*a*0.85
a = 0.3 m/s^2
