Question

Given s(t) = 1, where s is in miles and is in hours, find each of the following. a) v(t) b) aft) c) The velocity and acceleration when t he d) When the distance function is given by the linear function, there is uniform motion What does uniform motion mean in terms of velocity and acceleration? a) (t) = 1 b) alt=1 c) When t = 4 the velocity is miles per hour (Simplify your answer.) When t = 4, the acceleration is miles per hour squared (Simplify your answer.) d) What does uniform motion mean in terms of velocity and acceleration? Choose the correct answer below O A. The velocity and acceleration increase as the function increases O B. The velocity remains constant and there is no acceleration OC. The acceleration remains constant and there is no velocity OD. The velocity and acceleration decrease as the function increases

Answer 1

S(t) = t +1 @) V(t) = ds-d(t+1) dt at = 1+0=1 (6) act) = dv=d(1) dt de alt =0 (c) V (4) = 1 miles Im a(4) = 0 nitel / m2 (d) r(t)=1 =) velocity remains constant 4 there is no acceleration
