Does anyone have chegg? I need help with this question and that's the only platform that has full answer.
Question 1
Read each question carefully. Show all your work for each part of the question. The parts within the question may not have equal weight.
The figure presents a ball at the top of an inclined plane that slopes downward and to the right. The top of the inclined plane is 2.00 meters high, and the angle created by the surface and the inclined plane is 30.0 degrees.
A 250.0 g snowball of radius 4.00 cm starts from rest at the top of the peak of a roof and rolls down a section angled at 30.0 degrees to the horizontal. It then reaches a flat section of roof that is 2.00 m lower than the peak and is partially covered in snow, as shown above.
(a) On the dot below, which represents the snowball, draw and label the forces (not components) that act on the snowball. Each force must be represented by a distinct arrow starting on, and pointing away from, the dot. The force must start at the point on which it is exerted on the snowball. The dashed line represents the roof.
The figure presents a black dot along a dashed line that slants downward and to the right.
Question 2
(b) Which of the forces shown in part (a) produces a torque on the snowball as it rolls about its center? Justify your selection.
Question 3
(c) Calculate the linear acceleration of the snowball as it rolls down the inclined section of the roof.
Question 4
(d) Using conservation of energy, calculate the angular speed of the snowball as it reaches the end of the inclined section of the roof.
Question 5
(e) A second snowball with the same radius that is packed so that it is more dense than the original rolls down the same roof. Will the angular speed at the end of the incline for the new snowball be greater than, less than, or Equal to the original snowball?
Increase Decrease Stay the same
Justify your answer.
