<span>The formula to get the Kinetic Energy is KE=1/2mv^2 where m=mass in kilogram and v=velocity of the object. From you given, we substitute it to the variables. This is the solution: KE=1/2mv^2 KE=1/2(55kg)(9.0m/s)^2 KE=1/2(4455) KE=2227.5J or it can be written in scientific notation as 2.2275x10^3J or closest to your choices is 2.2x10^3J.</span>

Imagine you leave the dock on a fishing boat that travels east for 30 kilometers when the captain realizes he left the fishing r
telo118 [61]

Answer:

Average speed is 60 km/hr whereas average velocity is 0 km/ hr.

Explanation:

The average speed of the boat is 60 km/ hr while on the other hand, the average velocity of the boat is 0 km/ hr because average speed is the total distance covered by the boat in total time and average velocity is the displacement covered by the boat in total time. The total distance covered by the boat is 60 km and the total time is 60 minutes which is equals to one hour so the answer is 60 km/hr whereas the displacement is the shortest distance between initial and final position which is 0 in this case so 0 divided by 60 minutes or one hour is also 0.
