Question 1

Direction: In each of the following questions, a Statement of assertion is given followed by a corresponding Statement of reason.

Assertion (A) Linear momentum of a body changes even when it is moving uniformly in a circle.
Reason(R) In uniform circular motion velocity remains constant.

Question 2

A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field . Due to the force q, its velocity increases from 0 to 6 m/s in one-second duration. At that instant, the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively:-

Question 3

A ball of mass 2 kg and another of mass 4 kg are dropped together from a 60 feet tall building. After a fall of 30 feet each towards earth, their respective kinetic energies will be in the ratio of:

Question 4

A man throws balls with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two balls are in the sky at any time?
(Given g= 9.8m/s2)

Question 5

A ball is thrown from a point with a speed n0 at an angle of projection q from the same point and at the same instant, a person starts running with a constant speed n0/2 to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection?
