Question

study the graph and answer the following quedtions:
a) which paths have constant speed
b) when is the maximum speed reached
c) when is the acceleration happened
d) when is deceleration happened​

Answer 1

Answer:

a. ab and de

b. 15m/s

c. oa and bc

d. cd

Answer 2

Answer:

(a)  A to B and D to E

(b) Maximum speed - "C" i.e.15m/s.

(c) Acceleration -"o to A" and "B to C"

(d) Deceleration happens- "C to D"

Explanation:

In the graph we can see that the velocity is represented on the y-axis and time is represented on the x-axis.

Let's now address each question one at a time.

(a) The paths from A to B and D to E have a constant speed of 10m/s.

(b) The maximum speed reached point "C" i.e.15m/s.

(c) The acceleration happens from the point "o to A" and "B to C" as its speed is increasing at these points.

(d) The deceleration happens from the point "C to D".
