B. 350
C. 100
D.50

Answer 1

The answer is D.50

Hope i helped

Answer 2

Answer : The total displacement after 2 minutes is 50 m.

Solution :

Displacement : It is defined as the change in the position of an object. It is a vector quantity that means it has direction as well as magnitude.

In mathematical term, it is defined as,

`Displacement=\text{ change in position of an object}=\Delta x=x_(final)-x_(initial)`

By using this formula, we get the total displacement after 2 minutes.

Initial position, A = 0 m

Final position, C = 50 m

Now put the given values in above formula, we get

`Displacement=x_(final)-x_(initial)=50m-0m=50m`

Therefore, the total displacement after 2 minutes is 50 m.
