This can be done using a device like a speedometer or by using a stopwatch to measure the time it takes for the car to travel a certain distance. Then, use the equation a = (vf - vi)/t to calculate the acceleration. What factors can affect the acceleration of a car?
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. Accelerationa = (v-u) /t Or at = (v-u) Ort = (v-u) /a Next step is to substitute the equation for the time t into the second equation of motion s=ut +...

It's the simplest case because here, TT equals tt for any speed. To calculate the distance covered at constant acceleration during a certain time, you can use the following classical formula: d=12at2d=21at2 Since acceleration is constant, and we assume that the initial velocity equals zero,...
It confirms that this truncation error vanishes when Δt and Δx tend to zero; therefore the scheme in Eq. (11.74a) is consistent. The accuracy of the scheme is the first order in time and second order on space. The condition for consistency may be restated: a scheme is consistent if ...
The distance s in metres moved by a vehicle over a period of time t seconds is defined by the equation s = ut + ½at2, with a being the constant acceleration and u the initial velocity. Assuming the vehicle commences motion with an initial velocity of 5 m/s and covers 84 m with ...
t = 0:0.01:10; % consider a time vector for ball displacement (say 10s) x0 = 10; v0 = 15; a = -9.81; % acceleration x = x0+v0*t+0.5*a*t.^2; hold on plot(t,x); ylim([-50 50]) idx = t == 5; % find the index of 5s...
Derivatives are seen and discussed in real life as well. For example, the word speed is mentioned a lot, but very few know that speed is also a derivative, speed is the change in the distance with respect to time. The following are the applications of derivatives: To calculate the ...
pmo is the amplitude of the pressure wave, r is the radial distance from the center of the pipe to any point, a is the radius of the pipe, z is the distance along the pipe, ω is the radian frequency, and t is time. γom and αom are related by the following formula: γom=k2...
In contrast to more familiar mechanical systems in which a force gives rise to an acceleration, F=mX¨0, the vortex dynamics in the rigid model approximation is manifestly non-Newtonian. The response of the vortex to a force involves motion in a direction perpendicular to this force. For a ...
