Q1. A plane leaves the airport in Galisto and flies 165 at 68.0 east of north and then changes direction to fly 230 at 48.0 south of east, after which it makes an immediate emergency landing in a pasture.
Q2. An object with a charge of -3.1 mu C and a mass of 1.7×10-2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Find the magnitude of the electric field.
On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts an 8020-N force on the plane, focussed upward at the angle of 55.0° above the horizontal. The plane rises with constant velocity in the vertic..

Two identical carts travel at 1m/s in opposite directions on a common horizontal surface. They collide head-on and are reported to rebound, each with the speed of 2m/s.
A conveyor belt at a quarry lifts 2,000 kg of sand per minute up a vertical distance of 12 meters. The sand is at first at rest, then moves at a speed of 0.20 m/s along conveyor belt. What is the instantaneous power generated by this machine .
A second fragment, who's mass is 3.4 kg, moves away from the point of explosion with a speed of 418 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity.
A mass m = 90 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 18.8 m and finally the flat straight section at the same height as the center of the loop (18.8 m off the ground). Because the mass would not..
