Q1. An airplane is flying with a velocity of 89.0 at an angle of 18.0 above the horizontal. When the plane is the distance 112 directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog would the suitcase land? You can ignore air resistance.
Q2. A massive steel cable drags a 21.0 block across a horizontal, frictionless surface. A 90.0 force applied to the cable causes the block to reach a speed of 4.10 in 1.70 .What is the difference in tension between the two ends of cable?
The coefficient of static friction between the 3000 lb car's tires and the road is 0.5. Determine the steepest grade the car can drive up at constant speed if car has (a) rear=wheel drive; (b) front-wheel drive; (c) four wheel drive.
A spring stiffness 900 N/m and relaxed length 1m stands vertically on a table. You hold a block of mass 1 kg barely touching the top of the spring. Assume you let the mass down onto the spring certain distance very slowly and view the mass is not mov..

A vessel whose walls are thermally insulated contains 2.00 of water and 0.550 of ice, all at a temperature of 0.0. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
Coherent light with wavelength 599nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00m from the slits. The first-order bright fringe is a distance of 4.84mm from the center of central brigh..

A particular guitar string is supposed to vibrate at 214 Hz, but it is measured to actually vibrate at 272 Hz. By what percentage must the tension in string be changed to get the frequency to the accurate value.
A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 4.50 m/s in 0.852 s. What are the magnitudes of the linear impulse and the average total force experienced by a 65.0 kg passenger i..
