Can a body have constant acceleration and zero velocity?

Since the derivative of velocity is acceleration, the answer would be technically 'no'. Here is why: v = 0 v' = 0 = a Or in variable form... v(x) = x v(0) = 0 v'(0) = 0 = a You can "trick" the derivative into saying that v'(x) = 1 = a (since the derivative of x = 1) and then stating v'(0) = 1 = a... but that is not entirely correct. Acceleration is a change over time and is measured at more then one point (i.e. the acceleration of this body of matter is y from time 1 to 5) unless using derivatives to form the equation of the acceleration line/curve. If an object has a constant acceleration of 1, then the velocity is constantly increasing over that time. Using the equation discussed above and looking at acceleration over time, at 0 seconds, acceleration is 0 and so is velocity, but from 0-1 seconds acceleration is 1 and velocity is 1 as well. 0-2 seconds, acceleration is 1, but velocity would be 2 (at the end of 2 seconds).


When acceleration is 0 why does velocity have to be at a maximum?

It doesn't. If acceleration is zero, that just means that velocity isn'tchanging ... the motion is in a straight line at a constant speed.


What acceleration does a rocket need to reach a speed of 230meters per second at a height of 1.0km?

To calculate the acceleration of the rocket, you can use the kinematic equation: (v^2 = u^2 + 2as), where (v) is the final velocity (230 m/s), (u) is the initial velocity (0 m/s assuming the rocket starts from rest), (a) is the acceleration, and (s) is the displacement (1000 m). Rearranging the equation to solve for acceleration, you'd get (a = (v^2 - u^2) / 2s). Plugging in the values, you'd get (a = (230^2 - 0^2) / (2 * 1000) = 264.5 m/s^2). The rocket would need an acceleration of 264.5 m/s^2 to reach a speed of 230 m/s at a height of 1.0 km.


When velocity is zero and acceleration is less than zero does the speed increase?

if acceleration is <0 and velocity =0 then you got the handbrake on


Can your speed be 0 while your acceleration non zero?

Yes, it is possible for the speed to be 0 while the acceleration is non-zero. This occurs when the object is momentarily at rest (speed is zero) while still experiencing acceleration due to a change in its velocity.

When an object is accelerating constantly how to find the acceleration?

When the acceleration is constant then s= 1/2 at^2 and the acceleration is a=2s/t^2.


How do you calculate acceleration when given velocity and distance?

v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration


If the universe was expanding with 0 acceleration what would the age of the universe be?

The universe simply cant expand at 0 acceleration.

A sprinter accelerates from 1 ms to 3ms in 2s?
