Answer:
The velocity of the particle will be zero for t = 1.47 sec .
Step-by-step explanation:
Given equation:
a(t)=t+sin(t)
lets integrate it with respect to time,
∫ a(t) dt = ∫(t+sin(t)) dt
⇒ v(t) = - cos(t) +c
At, t=0, v= -2 so,
⇒ -2 = 0 - 1 +c
⇒ c= -1
Hence,
v(t) = - cos(t) -1
for the velocity to be zero,
0 = - cos(t) -1
⇒ t = 1.47 sec (taking only positive value)
So at 1.47 sec the velocity of particle will be zero.

Answer:
3 * 6 = 18
Step-by-step explanation:
53 * 26 =
= (50 + 3) * (20 + 6)
= 50 * 20 + 50 * 6 + 3 * 20 + 3 * 6
= 1000 + 300 + 60 + 18
Answer: 3 * 6 = 18
Answer:
it is 8 i had the same question
Step-by-step explanation:
Answer:
1 5/8
Step-by-step explanation:
6 1/8 = 6x8=1 = 49/8
4 1/2 = 4x2+1 = 9/2
so, 49/8 - 9/2 = 13/8
which in alternative form is 1 5/8 or 1.625
