Question

if v=(t+10)m/s. find displacement of particle as function of time

Answer 1

ANSWER

At t=0, the particle is at a position 5 m, and at t=4 s the particle is at position 1 m.

Thus displacement of particle S=1−5=−4 m

Time taken t=4 s

Average velocity V

=−1 m/s

Slope of displacement-time graph gives the velocity of particle at that instant.

Slope of the graph is zero at t=4 s, thus velocity is zero at t=4 s.
