A cargo plane in flight lost a package because somebody forgot to close the rear cargo doors. You are on the team of safety experts trying to analyze what happened. From the point of takeoff, while climbing to altitude, the airplane traveled in a straight line and at a constant speed of 283 mi/h at an angle of 41°above the horizontal. During the ascent, the package slid off the back ramp. You found the package in a field a distance of 8.3 km from the takeoff point. To complete the investigation you need to know exactly how long after takeoff the package slid off the back ramp of the plane. (Consider the sliding speed to be negligible.) Calculate the time at which the package fell off the back ramp. (Ignore any effects due to air resistance.)
In a physics lab experiment, a student immersed 201 one cent coins (each having a mass of 3.00) in boiling water. After they reached thermal equilibrium, she quickly fished them out and dropped them into 0.240 of water at 20 in an insulated contai..
Kelli weighs 405 N, and she is sitting on the playground swing that hangs 0.43 m above the ground. Her mom pulls the swing back and releases it when the seat is 1.00 m above the ground. suppose that air resistance is negligible.
After collision, the component of the total momentum parallel to the floor must remain zero, since the net external force acting on the plate has no component parallel to floor.find out the masses of pieces 1 and 2.
Airtight box has a removable lid of area 1x10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.85x 10^5Pa. The inside of the box is completely evacuated. What is the magnitude of the force essen..
