Answer: The velocity at different marked time points are given as
t1 = -
t2 = +
t3 = +
t4 = -
t5 = 0
Explanation:
The slope of the tangent of the curve indicates the instantaneous velocity. So if the slope of the tangent is positive, that Is, the tangent makes a positive angle (above the horizontal axis) with the horizontal
axis, then the velocity at this point is positive, and if the slope of the tangent is negative, that is the tangent makes a negative angle with the horizontal axis (below the horizontal axis), then the velocity at this point is negative.
When the tangent of the line is parallel to the horizontal axis, the velocity is 0.
From the position-time graph attached, the sign on the instantaneous velocity for each time marked on the graph is given below
t1 = -
t2 = +
t3 = +
t4 = -
t5 = 0

Answer:
Explanation:
Given
Required
Determine the linear equation for P in terms of h
First, we calculate the slope/rate (m);
The following formula is used:
Substitute values for P's and h's
Multiply by 1000/1000
The equation is then calculated using:
Substitute values for m, h1 and P1
Make P the subject
<em>The above is the required linear equation</em>
