If the time of ascent is half of the time of descent, the friction coefficient μ is equal to A particle is projected up a rough inclined plane of inclination θ and friction coefficient μ. If the time of [...]

A ball is thrown vertically upwards with a velocity of 10 ms−1. It returns to the ground with a velocity of 8 ms−1. If g=9.8 ms−2 , then the maximum height attained by the ball is nearly (assume air resistance to be uniform) A ball is thrown vertically upwards with a velocity of 10 ms−1. [...]

Two objects A and B are thrown upwards simultaneously with the same speed. The mass of A is greater than the mass of B. Suppose the air exerts a constant and equal force of resistance on the two bodies. Which object will go high? Consider a car moving on a straight road with a speed [...]

In an imaginary atmosphere, the air exerts a small force F on any particle in the direction of the particle’s motion. A particle of mass m projected upward takes a time t1​ in reaching the maximum height and t2​ in the return journey to the original point. Then Consider a car moving on a straight [...]
