Q1. An airplane flying at 115 m/s due east makes a gradual turn while maintaining its speed and follows a circular path to fly south. The turn takes 15 seconds to complete. What is the radius of circular path?
Q2. For a damped oscillator with a mass of 180 g, a spring constant 58 N/m and a damping coefficient of 60g/s, what is the ratio of the amplitude of damped oscillations to the initial amplitude at the end of 26 cycles?
A 150 g ball and a 250g ball are connected by a 35{rm cm}-long, massless, rigid rod. The balls rotate about their center of mass at 150 rpm.
A 362 g object is attached to a spring and executes simple harmonic motion with the period of 0.200 s. If the total energy of the system is 6.71 J.
How long after being thrown will the balls collide
Two heavy pendula of mass m are suspended from strings of length l inside a railroad car of mass M that can roll freely on horizontal tracks (ignore the moment of inertia of the wheels).
An archer shoots an arrow horizontally at the target 14 m away. The arrow is aimed directly at the center of target, but it hits 59 cm lower.

Suppose the gravitational force between two massive spheres is 100 N. If the distance between the spheres is doubled, what is the force between the masses.
Two packages at UPS start sliding down a ramp 40 degrees from the horizontal, Package A is sliding down in front of Package B. Package A has a mass of 3.50 and a coefficient of kinetic friction of 0.220. Package B has a mass of 8.00 and a coefficient..
A fuel leak is discovered at this point, and crew calculates that the plane can safely fly no more than 170 km before an emergency landing should be attempted. The only appropriate location for an emergency landing is 100 km north of their current po..
What is magnitude of the linear acceleration of the hoop . Elucidate using Newton's Second Law of Motion, why you can throw a golf ball further than a bowling ball, still though you throw both at the similar angle and with the same amount of force.
Velocity and time for the moving particle.
