Achild uses a rubber band to launch a bottle cap at an angle of 37.0° above the horizontal. the cap travels a horizontal distance of 1.30 m in 1.20 s. what was the initial speed of the bottle cap, just after leaving the rubber band, in m/s

Initial velocity will be 1.356 m/sec      

Explanation:

Let the initial speed = u

Angle at which rubber band is launched = 37°

Horizontal component of initial velocity

Time is given as t = 1.20 sec

Distance in horizontal direction = 1.30 m

We know that distance = speed × time

So time

So initial velocity will be 1.356 m/sec

im guessing the west of station b

i don't understand. explain it clearly
