If a ball is shot out at 5.4m/s and makes an angle of 30 degrees with the horizontal, the x component would be 5.4cos30 and the y component would be 5.4sin30 correct?
The question then asks me to write an expression for the ball’s velocity, v, using unit vectors for the x-direction and the y-direction. Wouldn’t the velocity be just 5.4m/s? I don’t understand wht they are asking.
