Which of the following statements about this lab are true? You should take the average of the acceleration data in an appropriate time interval. Logger ProTM will report the angle, angular velocity and angular acceleration of the big wheel, not the rotation sensor. If the large wheel is rotating clockwise, the friction from the large wheel's bearings will cause a clockwise angular acceleration. We assume the sensor wheel is massless and does not affect the accelerations measured.

Mass of Little Sister = 44.17 kg
Explanation:
From Newton's second law of motion, the magnitude of force applied on the sled is given by the following formula:
F = ma
where,
F = Force Applied = 120 N
a = Acceleration = 2.3 m/s²
m = Mass of Sled + Mass of Little Sister = 8 kg + Mass of Little Sister
Therefore,
120 N = (2.3 m/s²)(8 kg + Mass of Little Sister)
(120 N)/(2.3 m/s²) = 8 kg + Mass of Little Sister
Mass of Little Sister = 52.17 kg - 8 kg
Mass of Little Sister = 44.17 kg
