Velocity time graph of an object of mass...

Velocity time graph of an object of mass 2kg is shown in figure. The force required to move the object for first four seconds is

A

0N

B

4N

C

2N

D

8N

Text Solution

Verified by Experts

The correct Answer is:
B
The given velocity time graph is a straight line with a positive slope . Thus object has a constant acceleration a= slope of this line
`((8-4)m//s)/((4-2)s)=2ms^-2`
`implies Force=m times a=2 times 2=4N`
