Sketch a distance-time graph for a body starting from rest how will you determine the speed of a body from this graph?
It is not possible to sketch anything using this browser. The speed of a body cannot be determined from a distance-time graph. The slope of the graph is a measure of the radial velocity - that is the speed directly towards or directly away from the starting point. However, there is absolutely no information of any motion in a transverse direction. Since motion in this direction cannot be assumed to be 0, the distance-time graph cannot be used to determine speed.
How is math used in orthopedic surgery?
Most likely a surgeon needs to be able to do basic trigonometry and arithmetic in order to make sure that ratios between body parts are correct and that joints have the proper angles to maintain proper body function. On top of this they may also need to be able to determine volumes of certain shapes when transplanting body tissue from one part of a body to the other.
A remote control car's wheel accelerates at 22.4 rad-sec squared If the wheel begins with an angular speed of 10.8 rad-sec what is the wheel's angular speed after exactly 3 turns?
A measure of how fast a rotating body is changing its angular position. The average angular speed (w) is obtained by dividing the http://www.answers.com/topic/angular-distance-2 through which the body rotates by the time taken: w = θ/t, where θ = angular distance, and t = time taken in seconds.
A body travels with average speed of 20 km per hour and returns back from same route of average speed of 30 km per hour What is average speed of the trip?
Assume the trip to be 60km. Outward leg takes 3 hrs, homeward leg takes 2 hrs. Total distance 120km in 5 hours ie 24 kph.
Can velocity be 0 but speed not 0?
Yes, velocity can be 0 while speed is not 0. Velocity is a vector quantity that includes both speed and direction, so if an object is moving in a straight line and comes to a stop, its velocity is 0 but its speed is not 0. Speed, on the other hand, is a scalar quantity that only considers the magnitude of the motion, regardless of direction.
