Question

Solve below

What is the instantaneous velocity v of the particle at t = 10.0 s? Express your answer in meters per second. Another common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors have only one nonzero component in the direction of motion. Thus, in this problem, we will call v the velocity and a the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion.

Explanation / Answer

Here expression for displacement is not given.

Instantenous velicity at t=10s is

ds/dt & put t=10 after differentiating.
