If the displacement of a particle executing SHM be 10 cm and 12 cm when the
corresponding velocities are 16 cms
−1
and 14 cms
−1
respectively, calculate the amplitude
of motion.

Write the equation of motion of a simple harmonic oscillator which has an amplitude of
5 cm and it executes 150 oscillations in 5 minutes with an initial phase of 45°. Also
obtain the value of its maximum velocity.

The displacement of a particle is zero at t=0 seconds and it is x at t seconds. it stars in a positive x direction with a velocity that varies v=k√x where k is a constant . Show that velocity varies with time.

By making assumptions, what would happen if suddenly the weather at Sepang (place name) is rainy and all the F1 team need to continue the face (F1 race)? Discuss all the risks and suggest any alternative idea to reduce the problems.

a body starting from rest travels with uniform acceleration. if it ravels 100 m in 5 seconds what is the value of acceleration?

a bullet is fired horizontally at a velocity 10m/s from a watch tower 100m high. how long does it take to reach the ground?(g=9.8m/s^2)

A bird flies in the east direction with a speed of 5 ms−1. The wind is blowing towards north at a speed of 3 ms−1. Determine the relative velocity of the bird with respect to the wind. Draw appropriate diagram for solving the problem.

Find the value of ''g'' by free fall method when the distance between initial and final positions is 0.7m and average time for 15 vibrations is 24 secon
