Question

what would be a shape of speed time graph of a body moving with variable speed

Answer 1

Answer:

Non uniform almost the shape of this time graph

Answer 2

Answer:

Here's the answer :

Explanation:

The slope of the graph would not be parallel to the time axis as with unit change of time, the speed is not constant. If the speed is increasing uniformly with unit change in time, then the slope of the graph will go upwards. But, if the speed is uniformly decreasing then, the slope of the graph will go down towards the time axis. However, if ds/dt is not constant (i.e. change in speed is not uniform) then the slope will be non-linear.

I hope this helps.
