Question
Position time relation of a particle is given by x = (3t + 4)m. Find the velocity of particle from the graph.
Solution
Position of a particle at any instant, x = 3t+4
The x -t graph is a straight line.
The slope of the position-time graph gives us the velocity of the particle.
Here, slope of the graph is,
Therefore, velocity of the particle is 3 m/s.
