Homework Help: math

Posted by Kay on Thursday, June 23, 2011 at 8:08pm.

Can you please check my work.

A particle is moving with the given data. Find the position of the particle.
a(t) = cos(t) + sin(t)
s(0) = 2
v(0) = 6

a(t) = cos(t) + sin(t)
v(t) = sin(t) - cos(t) + C
s(t) = -cos(t) - sin(t) + Cx + D

6 = v(0) = sin(0) -cos(0) + C
C=7

2= s(0) = -cos(0) - sin(0) + 7 (0) + D
D= 3

s(t) = -cos(t) - sin(t) + 7t + 3
