The graph represents velocity over time.

a graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). a line runs from 0 seconds 2 meters to 100 seconds 22 meters.

what is the acceleration?

–0.4 m/s2
–0.2 m/s2
0.2 m/s2
0.4 m/s2

Acceleration is 0.2 m/s².

Explanation:

From the graph below,

The x axis represents the time and the y axis represents the velocity.

Now, acceleration of an object is given as:

Acceleration,

Now, from the below graph,

Change in velocity is,

Time interval is,

Therefore, .

Acceleration is 0.2 m/s².

answer: a. same unit

explanation:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
