You roll a car along a flat track, but find the acceleration is different traveling one direction as compared to the other because one direction was uphill (slightly) and the opposite direction was downhill (slightly). This means that aexperiment= atrack ± aℎill where the plus/minus depends on whether it's uphill/downhill. If you find acontrol = −3.5 cm/s^2 and aopposite=−6.7 cm/s^2 , what is atrack and what is aℎill in this case?
Homework Answers
given
aexperiment= atrack ± aℎill
a(control)=a(track) + a(ℎill)=−3.5cm/s^2
a(opposite) = a(track) - a(ℎill)== −6.7cm/s^2
add above two equation
2a_track = - 10.2 cm/s^2
a_track= - 5.1 cm/s^2
a_control=- 5.1 cm/s^2 + a(ℎill)=−3.5cm/s^2
a_ℎill = + 1.6 cm/s^2

A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
