A bowling ball is rolled down the alley with a constant velocity of 1.5m/sec. at an angle of 87 degrees to the starting line. The position of the person throwing the bowling ball can be represented by the point (0,0). Where is the ball after 7 seconds?

Respuesta :

Unknownly
The ball is at (0.5,10.5) after 7 seconds. 

Answer: (10.485, .549)

Distance traveled in 7 seconds along the inclined plane = 1.5 * 7 = 10.5 m

Angle formed are 87, 3 and 90.

Considering the right triangle and applying the cos and sin values, we can find values of distance traveled horizontally and distance traveled vertically.

sin 3 = y/10.5

y = 0.549

cos 3 = x/10.5

x = 10.485
