Part - A

Generic 5 - Answer All Question

A monkey hangs on a tree. A hunter aims a gun at the monkey and fires the bullet with velocity Vo which makes angle \(\alpha\)o with horizontal direction. At the instant gun fires, monkey leaves the branch and falls straight down to escape from the bullet as shown in the figure. Will bullet hit the monkey or will the monkey escape the bullet? (ignore air resistance)

The position of an particle is given by x = 6t + 2t³. Find out that its motion is uniform and non uniform.

A train moving with a speed of 100 km/h can be stopped by brakes after atleast 15m. What will be the minimum stopping distance, if the same train is moving at a speed of 120 km/h?

A train 20 m long is moving with a speed of 40 km/h. In what time shall it cross a bridge of 500 m long?

Explain triangular law of addition method.

A bus starting from rest moves with a uniform acceleration of 0.2 ms^-2 for 3 minutes. Find the speed and distance travelled.

Derive the equation of motion, range and maximum height reached by the particle thrown at an oblique angle \(\theta\) with respect to the horizontal direction.

Derive the expression for total acceleration in the non uniform circular motion.

Chennai is at a distance of 500 km from Coimbatore. (A) sets out from Coimbatore at a speed of 50 kmh^-1 and (B) sets out at the same time from Chennai at a speed of 40 kmh^-1, When will they meet each other?

A swimmer moves across the Cauvery river of 750 m wide. The velocity of the swimmer relative to water (\(\vec{v}\) _sw) is 1.5 ms^-1 and directed perpendicular to the water current. The velocity of water relative to the bank (\(\vec{v}\)wb) is 1 ms^-1. Calculate the
(a) velocity of the swimmer with respect to the bank of the river (\(\vec{v}\)_sb).
(b) time taken by the swimmer to cross the Cauvery river.

Write the important properties of vector (cross) product?

If position of a particle at instant t is given by x = 3t², find the velocity and acceleration of the particle.
