Question

Study the v-t graph and answer the following questions.


Identify the portion where the object is in accelerated motion.
Find the acceleration of the object at the instant AB
Find the Retardation from the graph

Answer 1

Explanation:

Here, 1. The slope of the line at a particular time gives the acceleration of the object at that time....

2.Area under the graph gives the displacement of the object....

According to the question:-

Acceleration = Slope

Slope = (4-0)m/s /4 = 1m/s²

2. Acceleration = Slope

(0-4)/4m/s = -1m/s²

3. Distance = (1/4×2×2)m =8m

Answer 2

Explanation:

1. Here, the slope line at a particular time gives the acceleration of the object at that time....
2. Area under the graph gives the displacement of the object....

ATQ:-

• Acceleration = Slope

• Slope = (0-4)m/s¹/4 = 1m/s²

• Distance = (¼ × 2 × 2) = 8m
