Question

A particle moves in a straight line under an
acceleration varying linearly with time. Its
velocity-time graph is shown in figure. Then
v (m/s)
velocity vs t graph having max height at 3s(graph makes 37 degrees with y axis and 45 degrees with x axis
(1) The particle comes to rest at t = 7 s
(2) The initial velocity of particle is 1 m/s
(3) Maximum velocity of particle is 2 m/s
(4) The acceleration of particle is zero at t = 3 s​

Answer 1

Explanation:

particle moves in a straight line under an

acceleration varying linearly with time. Its

velocity-time graph is shown in figure. Then

v (m/s)

velocity vs t graph having max height at 3s(graph makes 37 degrees with y axis and 45 degrees with x axis

(1) The particle comes to rest at t = 7 s

(2) The initial velocity of particle is 1 m/s

(3) Maximum velocity of particle is 2 m/s

(4) The acceleration of particle is zero at t = 3 s
