the speed boat has a acceleration of 2.0 m/s2 if the initial velocity of the boat is 6.0 m/s2. find the boat displacement after 8.0 seconds?

Answer 1

x = 6 t + (1/2)(2) t^2

= 6(8) + 64

= 112 meters

Answer 2

car 1 travel from left to right and covers a distance of 1.609m(1mile) in a time of 4.740seconds. car 2 covers the same distance in 4.695seconds in the same direction. determine the average velocity for each car?

Answer 3

1609/4.740
and
1609/4.695
