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?

3.9 feet = 1.18872m and 14.8 feet per second=4.51104 meter per second

now,v=u+at 0=4.51 + (9.81)t t=0.46seconds

sauravshakyaBest ResponseYou've already chosen the best response.2
Again, v^2=u^2+2as 0^2=(4.51)^2 + 2(9.81)s s=1.04 m

sauravshakyaBest ResponseYou've already chosen the best response.2
So, maximum height = 1.19+1.04 m = 2.23m

sauravshakyaBest ResponseYou've already chosen the best response.2
Now, s=ut+1/2 at^2 2.23 = 0*t + 1/2 (9.81) t^2 t=0.67 seconds
 one year ago

sauravshakyaBest ResponseYou've already chosen the best response.2
So, total time = 0.46+0.67 =1.13 seconds
