Question

3. The velocity -time graph of a moving object is given below. a. What is the distance travelled by the object in first 2 seconds? b. What is the acceleration of the object between the time intervals 2s to 5s? c. What is the nature of motion between the time intervals 5s to 6s?

Answer 1

From graph we can calculate distance as area under curve so

a : distance = 1/2 x 2 x 15 = 15 m

b : we can see from the graph that since the body is moving with constant velocity therefore acceleration is zero

c : In 5 to 6 sec the body is retarding and ultimately velocity is zero
