A juggler is performing an act by juggling several balls. The juggler throws the balls up at an initial height of 3.9 feet with a speed of 14.8 feet per second. If the juggler did not catch a ball, about how long will it take the ball to hit the floor?

Question

anonymous · Answer

$$s=ut + (1/2)gt ^{2}$$, put s= +3.9ft u=-14.8ft/s and $$g= 32.2ft/s ^{2}$$

which gives t= 1.133 seconds..

32.2 is gravity pulls down on an object down right

anonymous · Answer

yeah, its the value of g, acceleration due to gravity, in ft/sec2

anonymous · Answer

yep the displacement s = -3.9 and g = - 32.2

equation is
-3.9 = 14.8t - 16.1t^2
answer is 1.133 secs
