Question

Silvia is driving at the speed limit of 25 m/s when she sees an ambulance approaching in her rear view mirror to the move out of its way , she accelerated to 32 m/s in 3 s . How far did she travel during those 3 s

Answer 1

KINEMATICS

Uniform or constant motion in a straight line (rectilinear). Speed or velocity constant and/or acceleration constant. If motion is up and down and/or has an up and down component then acceleration omn earth will be g. g is about 10m/s/s.

speed = distance/time

velocity = displacement/time

s=distance ... u=initial speed ... v = final speed ... a = acceleration ... t = time

v=u+at

v^2=u^2+2as

s=ut+1/2at^2
