1. Assume you are walking in front of a motion sensor that graphs the distance you have walked (y axis) against time (x axis). Describe the motion that you need to make to produce the following graphs:
a) Line with a positive slope.
b) Line with steeper positive slope.
c) Line with negative slope.
d) Line with zero slope.
e) A Parabola
2. An object is released (from rest) at the top of an inclined plane. After time t, the object has moved a distance d down an incline. What is its acceleration?
4. If m1g-T1=m1a, and T2-m2g=m2a, and (T1-T2)R=Iα
Solve these equations simultaneously to arrive at the following equation: (m1-m2)g=(m1+m2+( I/R^2))a
5. If m1g-T1=m1a, and T2=m2a, and (T1-T2)R=Iα
Solve these equations simultaneously to arrive at the following equation: m1g=(m1+m2+( I/R^2))a© BrainMass Inc. brainmass.com October 25, 2018, 2:46 am ad1c9bdddf
This solution provides steps necessary to determine the acceleration of the object rolling down an incline.
Linear velocity of cylinders when rolling down an incline
A thin cylindrical shell and a solid cylinder have the same mass and radius. The two are released side by side and roll down, without slipping, from the top of an inclined plane that is 4.9 m above the ground. The acceleration of gravity is 9.8 m/s2 :
Find the final linear velocity of the thin cylindrical shell. Answer in units of m/s.
Find the final linear velocity of the solid cylinder. Answer in units of m/s.
