b)What is the displacement in one revolution?
c)What does the speedometer of the car measure?
d)Can a body have acceleration without velocity.Explain.

Consider a particle moving along the circumference of a circle of radius R with constant speed with a time period T. During T, what is the distance and displacement covered?

Consider a particle moving along the circumference of a circle of radius R with constant speed with a time period T. What is the direction of the velocity at each point?

A car moving along a straight highway with speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?

An insect trapped in a circular groove of radius 12cm moves along the growth steadily and completes 7 revolutions in 100s. Is the acceleration vector a constant vector ? What is its magnitude?

A projectile is an object projected into air with a velocity V so that it is moving under the influence of gravity. a)What is the shape of the path of projectile? b)As a projectile moves in its path,is there any point along the path where the velocity and acceleration vectors are perpendicular to each other. c)If E is energy with a projectile is projected, (i)What is the kinetic energy at the highest point. (ii)What is P.E at highest point?

Uniform circular motion is a special case of two dimensional motion having centripetal acceleration. a)Define centripetal acceleration. b)Can a body have acceleration with constant speed?Explain. c)Express angular velocity in terms of angular displacement.
