Question

1
)- The velocity-time graph of an object of mass m = 100 g is shown in

figure. Observe the graph carefully and answer the following

questions.

(a) Calculate the force on the object in a time interval 0 to 3 s.

(b) Calculate the force on the object in the time interval 6 to 10 s.

(c) Is there any time interval in which no force acts on the object?

Justify your answer. ​

Answer 1

Answer:

Justify your answer. Answer: (a) Acceleration during interval 0 to 3 s Given mass, Force, (b) Acceleration during interval 6 to 10 s Force, (c) During time interval 3 to 6 s, the velocity of object is constant, so in this time interval, acceleration is zero and hence force, F (= ma) is zero.]
