Q1. An airplane is flying with a velocity of 82 at an angle of 25 above the horizontal. When the plane is a distance 125 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance.
Q2. A flat disk 1 m in diameter is oriented so that a plane of the disk makes an angle of pi/6 radians with a uniform electric field. If the field strength is 491N/C, find out the electric flux through surface.
David is driving a steady 28.0m/s while he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.70 at the instant when David passes. How far does Tina drive before passing David.
calculate the total mechanical energy of the glider at any point in its motion. Calculate the maximum speed of glider.
A basketball star covers 2.6 m horizontally in a jump to dunk the ball. His motion through space can be modelled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02m when he leaves the floor. It reaches a..
A person walks 21° north of east for 3.30km. How far would another person walk due north and due east to arrive at the identical location.
A rectangle measuring 30.0 {rm cm} by 40.0 {rm cm} is located inside a region of a spatially uniform magnetic field of 1.30 T, with the field perpendicular to the plane of the coil. The coil is pulled out at a steady rate of 2.00 {rm{ cm/s}} travelli..
A motorist travelling at 17m/s encounters a deer in the road 49m ahead. If the maximum acceleration the vehicle's brakes are capable of is -7 m/s2. If his or her reaction time is 1.9987 s, how fast will (s) he be travelling when (s) he reaches dee..

Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
