PHYSICS PLS HELP A fishing boat leaves port at 04:30 h in search of the day’s catch. The boat travels 4.50 km[E], then 2.50 km[S], and finally 1.50 km[W] before discovering a large school of fish on the sonar screen at 06:30h.

Calculate the boat’s average speed.

Calculate the boat’s average velocity

Full solution pls!

the device is called “ rocket engine”

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
