Question 2
The position x of a particle with respect to time t along x-axis is given by x = 9t2 – t3 where x is in metre and t in second. What will be the position of this particle when it achieves maximum speed along the +x direction?
Question 3
A body is moving with velocity 30 m/s towards east. After 10 s its velocity becomes 40 m/s towards north. The average acceleration of the body is
Question 4
A body starts from rest and moves with uniform acceleration. The ratio of the distance covered in the nth second to the distance covered in n seconds is,
Question 5
A police party is moving in a jeep at a constant speed v. They saw a thief at a distance x on a motorcycle which is at rest. The moment the police saw the thief, the thief started at constant acceleration a. Which of the following relations is true if the police is able to catch the thief?
Question 6
A particle is projected with velocity v0 along x-axis. The deceleration on the particle is proportional to the square of the distance from the origin i.e., W = -ax2. The distance at which the particle stops is
Question 7
A metro train starts from rest and in 5s achieves 108km/h. After that it moves with constant velocity and comes to rest after travelling 45m with uniform retardation. If total distance travelled is395m, find total time of travelling.
Question 8
A body moving with uniform acceleration describes 4m in 3rd second and 12m in the 5th second. The distance described in next three second is–
Question 9
A bullet fired into a fixed target loses half of its velocity after penetrating 3 cm. How much further it will penetrate (in cm) before coming to rest assuming that it faces constant resistance to motion?
Question 10
An automobile, travelling at 40 km/h, can be stopped at a distance of 40 m by applying brakes. If the same automobile travelling at 80 km/h is applied with the same braking force, then the minimum stopping distance, in metres, is (assume no skidding):
