A block is launched up an incline plane. After going up the plane, it slides back down to its starting position. The coefficient of friction between the block and the plane is 0.3. The time for the trip up the plane:
a. is the same as the time for the trip down
b. is more than the time for the trip down
c. is less than the time for the trip down
d. cannot be found without knowing the angle of inclination
Homework Answers
When the book is launched up the incline it will travel as a projectile with concerned velocity and acceleration due to gravity.
However while sliding down, the motion will be hampered due to friction between the book and incline. This will decrease the effective acceleration and increase the time taken by the book to cover the same distance downward.
Option c is correct.
