What else can I help you with?
A car traveling in a straight line has a velocity of plus 9 point 5 m per s After 3 point 5 s its velocity is plus 9 point 0 m per s What is the car's average acceleration in this time interval?
Average acceleration = (change in speed) divided by (time interval)A = (9.0 - 9.5) / (3.5) = (-0.5) / (3.5) = 0.14286 meter/sec2
Why does the (second)2 occurs in the unit of acceleration?
The unit of acceleration is meters per second squared (m/s^2) because it represents the rate of change of velocity over time. The squared term indicates that the velocity is changing with respect to time, thus indicating the acceleration over a given time interval.
How do you calculate the size of the acceleration?
Acceleration is calculated by dividing the change in velocity by the time it takes for the change to occur. The formula for acceleration is: a = (v_f - v_i) / t, where a is acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time interval. The units of acceleration are typically meters per second squared (m/s^2).
How do you calculate distance traveled with force mass and time?
Time, velocity and mass do not provide enough information. If you are given a time interval, t, then you need the velocity at the start of the interval (= u) and at its end (v). Then F = m*(v - u)/t
Find the time interval of acceleration?
You want to take your change in velocity(Final Velocity - Initial Velocity)(Vi - Vf) (8.3 m/s - 5.0 m/s = 3.3m/s). The, you divide it by your average acceleration (0.50 m/s^2) (3.3m/s ÷ 0.50 m/s^2 = 6.6 m/s) So the Final Formula is t =(Vf - Vi) ÷ a

If a car increases its velocity from zero to 60 kilometer in 10 s its acceleration is?
You use the equation: acceleration=change in velocity/time interval a = 60 / 10 a = 6
Suppose that an object is traveling along a straight line Suppose that its velocity function is given by vt equals 4t2 -8t where t is in seconds Find the objects average acceleration along the time?
The object's instantaneous acceleration is (8t - 8) at any time.We can't calculate the average acceleration, because you haven't defined a periodof time over which to average it. We need the start and finish times in order tofind an average.
What is the acceleration from 0 to 2s?
The acceleration from 0 to 2s is the rate of change of velocity over that time interval. It can be calculated by dividing the change in velocity by the time taken. Mathematically, a = (v_final - v_initial) / t.
Formula for accleration?
There are several formulae that involve acceleration. The most basic one is the definition of acceleration, which is: a = (difference in velocity) / time This assumes constant acceleration. For non-constant acceleration, the more general formula is: a = dv / dt where "dv" is the difference in velocity, and "dt" is the time interval, with the additional assumption that it is a very small time interval. For more details, read an introductory calculus book, to understand the concept of "derivative".
How do you find time when given distance and acceleration?
Distance = (1/2 of acceleration) x (time squared)You can change this around to solve it for acceleration or time.(Time squared) = (distance)/(half of acceleration)Time = the square root of [ (2 x distance)/(acceleration) ]Be careful . . .This is only true if the distance and the speed are both zero when the time begins.
If the speed of an object changes from 121ms to 98 ms during a time interval of 12s what is the acceleration of the object?
Acceleration is equal to the change in velocity over the change in time [a=(vf-vi)/(tf-ti). a=(98m/s - 121 m/s)/(12s)=(-23m/s)/(12s)=-1.92m/s^2
Name 2 physical quantities that can be obtained from v-t graph?
well, the area under the curve between a time interval is equal to the distance traveled on that specific time interval. So one quantity is distance. As for another quantity, the answer would be velocity, but I think they may want a less obvious answer. A quantity out side of velocity could be instantaneous acceleration. This is given by the slope of the the tangent line to the velocity-time graph.Hope this helps you answer your question. Though I think the most simple way to understanding why is to take a course of calculus.
