PLEASE HELP. I WILL MARK YOU THE BRAINLIEST. A particle moves along the x-axis with velocity v(t) = sin(2t), with t measured in seconds and v(t) measured in feet per second. Find the total distance travelled by the particle from t = 0 to t = π seconds. A) 2
B) 1
C) 1/2
D) 0

Step-by-step explanation:

since v(t) = sin (2t)

then s(t) = -(1/2)cos(2t) + c , where s(t) is the distance

when t = 0,

s(0) = -(1/2)cos 0 + c

= c - 1/2

when t = π

s(π) = -(1/2)cos 2π + c

= c - 1/2

distance traveled = s(π) - s(0)

= c - 1/2 - (c - 1/2)

= 0

which is exactly what you would get.

Just a different way of writing it.

sorry if it isnt right

12cm

the answer is d

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
