Q. On a level road with its brakes on, a car traveling at 85 km/hr stops within 91 m when the brakes lock and the car slides.
Whats the acceleration of the car?
Whats the coefficient of the kinetic friction of the tires and pavement?
assuming the acceleration is constant throughout each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 7.00 s to 1.00 min.
What is speed of the wind what is coefficient of static friction
If you are in a car accident with an initial speed of 119 km/h and you are stopped by an airbag that inflates from the dashboard, over what distance should the airbag stop you for you to survive the crash.
A car started frm rest and accelerated for 5s at 6.00m/s2.Then it stayed at a constant speed for 20 s. It next slowed down at 3m/s2 until it came to a stop? how far did it travel during the first 5 s.
A stand, string, a paper or plastic cup, a nail, a roll of paper towels or similar sized paper, coloured sand, or some other dry powdery product, and a ruler or measuring tape.
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
A parallel plate capacitor has plates of area 2.0*10^3 and plate separation 1.0*10^4m. find the capacitance of this system if air fills the volume between the plates.
What is the electric potential energy of the system.
You are to program a robotic arm on the assembly line to move in a xy-plane. Its first displacement is; its second displacement is, of magnitude 6.51 and direction 62.7 measured in the sense from +x-axis toward -y-axis. The resultant of the two displ..
A 1.20 liter flask contains a certain quantity of ideal gas at 305 K. after that an equal number of molecules of the same gas are added to the flask, after which the absolute pressure is 1.30 times its unique value. What is the final temperature.
How would you describe why we have different atmospheric pressure on different level (height) of earth's atmosphere in molecular level (molecular behaviour and what causes such behaviour).
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 1.2 cm, and the toy is released. If the spring constant is 103 N/m, what is the magnitude of the spring force acting on the..
