Question

9.
If velocity v of a particle moving on a straight line
as a function of time t is given as v = 5 - t (m/s)
then the distance covered by the particle in first
10 s is
(1) 5 m
(2) 15 m
(3) 25 m
(4) 50 m​

Answer 1

Answer is 50m/s

velocity =s÷t

v=5m/s i,e 1second 5 metre

therefore in 10s particle travel

=10 ×5=50m/s
