Question

Pls solve this ques 9

Answer 1

Slope of velocity- time graph gives us acceleration.

Hence, to find the slope, we need two points on the graph.

(0,0) and (50, 100)

$Slope = \frac{y_2 - y_1}{x_2 - x_1}$

$Slope = \frac{100 - 0}{50 -0}$

Acceleration = 2 m/s^2 (upto 50 seconds)

Acceleration = - 2 m/s^2 (from 50 to 100 seconds)

The graph is attached with this solution.
