A cannonball is shot from a cannon at a launch angle of 35 and an initial velocity of 147 m/s Assuming No air resistance, what is the initial horizontal velocity of the cannonball.

A.)51.45 m/s
B.)147 m/s
C.)120 m/s
D.)9.8 m/s

The force will determine the acceleration.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?
