a. Point a b. Point B c. Point C d. Point D 2. If two bodies contact one another

Question

a. Point a

b. Point B

c. Point C

d. Point D

2. If two bodies contact one another without slipping, and the points in contact move along different paths, the tangential components of acceleration will be ___________ and the normal components of accelration will be _________.

a. the same, the same

b. different, different

c. the same, different

d. different, the same

3. Whe considering a point on a rigid body in general plane motion:

a. Its total acceleration consists of both absolute acceleration and relative acceleration components.

b. Its total acceleration consists of only absoulte accelartion componets

c. Its relative accelartion component is always normal to the path

d. None of the above

Please explain each one in detail.

Explanation / Answer

1): ans C IC is perpendicular from the both flat surfaces.

2): ans C tangential acceleration will be same as there is no slip and normal will be different as they move at different path.

3): ans A total acceleration consists of both absolute acceleration and relative acceleration.
