Answer:
addition
Step-by-step explanation:
if u add 5 to both sides, the -5 and the +5 would cancel out, leaving you with x=17
To Find :
Position vector at time 
and 
.
Solution :
r (t) = 2 (t −7)i + 12t j
Putting t = 5 s and t = 8 s, we get :
r(5) = 2( -2 )i + 60j
r(5) = -4i + 60j
r(8) = 2i + 96j
Now, to find speed differentiating the r(t) w.r.t t :
Hence, this is the required solution.
