Question

How do you find instantaneous acceleration?

Answer 1

dv/dt or d^2x/dt^2

Answer 2

Draw a line tangent to the point on the line where you want to know the instantaneous accelleration.

The slope of that line is the instantaneous accelleration.

If the slope is zero at time t=7s (straight line) - the accelleration is zero.

If the velocity doesn't change - the accelleration is zero - that's what accelleration is - the time rate of change of velocity.

Answer 3

@lostmermaid find the slope of the line at 10s and that will be your accel
