Best Answer

Initial speed = zero
Final speed = 210 m/s
Time = 3.8 seconds

Average acceleration = (change in speed) divided by (time for the change)

= 210/3.8

= 55.26 m/s2 (rounded)

Note: The driver was pressed back into his seat pretty good by this acceleration of 5.64 G's !

In physics what is variable acceleration and please give at least two examples of it?

if a body covered same distance in unequal interval of time the acceleration is produce this acceleration is called variable acceleration


What is the speed over a period of time?

Average speed = distance covered / time taken > SI units: metres per second (m/s)


What are two equations for speed?

Speed = (distance covered) divided by (time to cover the distance) Speed = (magnitude of acceleration) multiplied by (time the acceleration has acted)


If you know the acceleration of a car its initial velocity the time interval what can you predict?

Its final velocity, the distance covered.


How does average speed relate the distance covered and the time taken for travel?

Average speed = Distance covered/Time taken


How do you find time with only distance and acceleration when Vi and VF are 0?

The amount of time it would take an object to travel a distance with constant acceleration depends on its initial velocity, according to the equation: d = vit + 0.5at2 Where d is displacement, vi is initial velocity, t is time, and a is acceleration. Note: if the object starts from rest, its initial velocity, logically, is zero.


What is the similarity between constant speed and acceleration?

If the speed is constant then equal distances are covered in equal intervals of time If acceleration is constant then equal change in velocity occurs in equal intervals of time.


How do you calculate magnitude of acceleration without time?

vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a. vf2 = vi2 + 2ad vf2 - vi2 = 2ad (vf2 - vi2)/2d = a


How do you find the acceleration for a moving object?

Divide the change in position, (total distance covered) by the time it took. Xf = xi +at a = xf-xi / t That is the definition of velocity, not acceleration. Acceleration is rate of change of velocity. (vfinal - vinitial)/t for constant acceleration so vf equals vi + at. Or a equals dV/dt otherwise.


How far does a plane fly in 15 seconds while its velocity is increasing from 75 ms to 145 m s at a uniform rate of acceleration?

If it accelerates from 75 m/s to 145 m/s at a uniform rate, then its average speed duringthe acceleration is 0.5(145+75) = 110 m/s.Distance covered in 15 sec at average speed of 110 m/s = (15 x 110) = 1,650 m = 1.65 km.

Who is a modern day scientist that specializes in speed and acceleration?

Speed and acceleration are covered thoroughly in the first semester of Freshman Physics, and rather early in the semester at that. These are no longer topics in which there's a lot to be gained by a PhD specializing in them.
