Answer:

The position of ball is (0.78, 11.17) after 8 seconds.

Explanation:

A bowling ball is rolled down the alley with a constant velocity of 1.4 m/sec at an angle of 86 degrees to the starting line.

Horizontal Position:

$x=v\cos\theta * t$

Vertical Position:

$y=v\sin\theta * t$

$v=1.4\ m/s$

$\theta=86^\circ$

$t=8\ sec$

Substitute the value into formula

$x=1.4\cos86^\circ * 8$

$x=0.78\ m$

$y=1.4\sin86^\circ * 8$

$y=11.17\ m$

Hence, The position of ball is (0.78,11.17)
