a particle moves along a straight line with the relation between the time and distance ( 3. at what time will the acceleration b

The displacement S (in meters) of a particle is related with time t (in seconds) as S = 3 t 3 + 4 t 2 + 3 t + 2 The velocity of the particle when t = 3 sec is => 105 m/sec or 27 m/sec or 108 m/sec or 42 m/s..

What is the acceleration of a body at t = 4 sec whose displacement S(in metres) is related with the time as S = 3 t 3 - 5 t 2 - 4 t + 2? => - 62 m/sec 2 or - 72m/sec 2 or 72 m/sec 2 or 62 m/sec 2..

The equation (1) gives the relation between distance, time and average speed. This relation can be used for making distance-time tables and also to determine the position of any moving object at any given time. But it is a long a..

>At the time of sunrise and sunset, light from Sun has to pass maximum distance through Earth's atmosphere. As l r > l b red color is scattered least and can enter into our eyes. That is why sun looks red at the time of sunrise and sunset. Clouds are seen due..

The law of motion of a particle along a line defined by s ( t ) = 30 + 6 t + 10 t 2 , where s is in feet. Find its acceleration at time t = 4 sec. => 20 ft/sec 2 or 56 ft/sec 2 or 4054 ft/sec 2 or 10 ft/sec 2 or 110 ft/sec 2..

The parametric equations of the path of a moving particle are x = 2 t + 5, y = 3 t - 5. Find the path of the particle. => a straight line or a circle or an ellipse or a parabola..

The distance (S) moved by a body is given by, S = ut + 1 / 2 at 2 , where t is the time in seconds, u is the initial velocity and a is the acceleration. Solve for a . => a = 2 ( S + t 2 ) u t or a = 2 ( S - u t ) t 2 or a = 2 ( S - t 2 ) u t or a..

Question: The speed-time graph for a particle moving at constant speed is a straight-line ________ to the time axis. 1. parallel 2. perpendicular 3. aligned 4. inclined Answer: ..

Jeff increases his hours of basketball practice every week. The relation between the time of practice, y and the number of weeks, x was found to be y = 3 x + 1 . Draw the graph for the relation. => Graph A or Graph B..

Graphical Derivation of First Equation Consider an object moving with a uniform velocity u in a straight line. Let it be given a uniform acceleration a at time t = 0 when its initial velocity is u. As a result of the acceleration, its..
