Question

For the one-dimensional motion of a particle,
described by position x = t + cost (where t is time in
s and x is in m), the velocity of particle is zero at
time t equals to
(1) 0.3s
1251s
(3) 0.
25
(4) 1.57 s​

Answer 1

Answer:

( 4 )

Explanation:

x = t + cost

v = 1 - sint = 0

t = π/2 s = 1.57 s

choose ans. ( 4 )

Answer 2

Answer:

x = t + cost

v = 1 - sint = 0

t = π/2 s = 1.57 s

choose ans. ( 4 )
