Q. An 810 kg sports car collides into the rear end of a 2000kg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.5 m before stopping. The police officer, knowing that the coefficient of kinetic friction between tires and road is 0.80, computes the speed of the sports car at impact. What was that speed?
Q. Police determine skid marks 83 m long on the highway showing where the car made an emergency stop. Assume that the acceleration was -10 m/s2 (about the highest for dry pavement), how fast was the car going?
Consider an infant who weighs 100 newtons. During each year she grows so that each dimension of her body increases by 5%. How much would she weigh then.
Calculate the energy associated with the magnetic field of a 191 turn solenoid in which a current of 2.44. A produces a magnetic flux of 3.74 x 10-4 T • m2 in each turn.
What is the lift (in newtons) by reason of Bernoulli's principle on a wing of area 77 m^2 if the air passes over the top and bottom surfaces at speeds of 270 m/s and 140 m/s, correspondingly.
protons are projected with an initial velocity v0 = 10410m/s into a region where a uniform electric field E = 710 N/C is present. The protons are to hit the target that lies a horizontal distance of 1.27mm from the point where protons are launched..
How much work must this force do to stop the wheel. An electron moving along the x axis has a position given by x = 11te-1t m, where t is in seconds. How far is an electron from the origin when it momentarily stops.
What is an acceleration of the car
A 110 granite cube slides down a 45 degree frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 235 steel cube at rest. How high above the table should the granite cube be released to give the steel cube a..
A small radio operates on 3.00 V and has a resistance of 15 coulomb. At what rate does the radio use electric energy.
A person exerts a horizontal force of F = 169N in the test apparatus. (h = 0.32m.) Find the horizontal force M that his flexor muscle exerts on his fore arm.
An uncharged spherical conducting shell surrounds a point charge - q at its centre. Then a charge +3q is placed on the outside surface of shell.
An old hunting weapon was a rock on the end of a string. The hunter would swing the rock in horzontal circles and then throw it. If the rock had a mass of 2 kg and the 2 m long string breaks when the tension is 60N.
A uniform plank of length 4.30 m and weight 226 N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 437 N walk on overhanging part of the plank be..
