The actual motion of a connecting rod of a slider crank mechanism is

How are acceleration (a) and velocity (v) related to displacement (s)?

A body is moving with an acceleration a = 5bt, where t is time in seconds and b is a constant. If the body started with a zero velocity initially, then its final velocity after t seconds will be (t^2 means t squared)

There are 10 floors in a building of height h and assume each floor is equidistant from ground. A man on 7th floor drops a ball from his window (window is exactly in middle of 7th and 8th floor). The ball falls into a well (at the ground) whose water is h meters below the ground level. What is the velocity of the ball as it touches the water?

Velocity

time

The velocity time graph of a motion is horizontal straight line. Then

Slope of a v-t curve represents

Area under a v-t curve represents

An involute is defined as which of the following descriptions?.

A). The locus of a point on the cerumference of a circle that rolls without slipping on the circumference of another circle.

B). Locus of a point on a straight line which rolls without slipping onthe cirumference of a circle.

I think the answer should be "tangential to the circumference of Tyre". If not then please explain in details.

The particle has two accelerations. (1) Centripetal acceleration due to circular motion (2) Tangential to the circumference due to speeding up of car. The net acceleration will be vector sum of both. Actual direction between radial and tangential directions. Hence answer is (D) None of the above.
