A cylindrical object can roll down an incline, as shown in Figure 1. The incline is slightly less
than one meter in length. A group of students wants to determine the acceleration of the object
while it is rolling down the incline. The students have access to the following equipment.
• A stopwatch, which can measure time intervals up to 999 s with a precision of 0.01 s
• A clock, which can measure time intervals up to 12 hours with a precision of 1 min ute (60 s)
• A meterstick, which can measure lengths up to 1 m with a precision of 1 mm
• A pair of calipers, which can measure lengths up to 10 cm with a precision of 0.05 mm
(a) Assume the object moves with a constant acceleration as it rolls down the incline. Write an
equation that includes acceleration and quantities that can be measured or obtained from
measurements by using the available equipment in the list.
