The speedometer on a car’s dashboard reads instantaneous speed, not the average speed over your entire trip. Instantaneous velocity from slope The instantaneous velocity at any moment is the slope of the position versus time graph at that moment. In the example, at time t = 4 s the ...
Option (a) and (b) can be understood. When speed of the particle remains zero then it means paritcle is at rest in a time interval, hence velocity also remains zero and hence acceleration reamins zero during that interval of time.

If you are given an object's speed, you can definitely determine its velocity. True or false. A particle moves in a straight line with uniform acceleration. Its velocity at time t=0 is v_1 and at time t=t is v_2. The average velocity of the partic...
A runner runs around a track consisting of two parallel lines 96 m long connected at the ends by two semicircles with a radius of 49 m. He completes one lap in 2.0 minutes. What is his average speed? How do you calculate aver...
Obviously, the average strain rate increases linearly with the average drawing speed. It should be noted that, since strain is dimensionless, the units of strain rate are s− 1, and so on. Large changes in strain rate can have a significant effect on wire flow stress and as-drawn ...

where ω is the reference frequency, C is the speed of light, and P0 is the input power. As before, the intrinsic fiber properties are denoted by Aeff, n2, and α (attenuation in dB/km). The nonlinear phase shift in the hybrid span may be integrated to obtain: (11.18)ϕ¯NL∝...
