A bowling ball is rolled down and alley with a constant velocity of 1.4m/sec. at an angle of 86deg. 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 8 seconds?

(0.1,1.4)
(0.6,8.0)
(0.8,11.2)
(11.2,0.8)

I got D. Can someone help ? Is this right ?

  1. Scott

    not right

    HINT : total distance traveled is ... 8 s * 1.4 m/s

  2. Chris

    When I multiply that I get 11.2.
    So would it be C then?
