A ball rolls at a constant velocity of 1.2m/s at an angle of 45 degrees below?

Horizontal velocity ( x direction ) = v . cos 45˚ = 1.2 . 0.7071 = 0.848 m/s
x distance traveled in 1.65 s = 1.40 m
The y distance traveled will be the same ( because sin 45 = cos 45 ), but negative ... – 1.40
coords are ( 1.40 , –1.40 )
