31. A juggler maintains 10 balls in motion, making
each of them to rise at a height of 80 m from his
hands. To keep proper distance between them, the
time interval maintained by juggler would be
(1) 0.6 s
(2) 0.8 s
(3) 1.0 s
(4) 1.2 s

Answer:
❤️❤️0.8 s
So, the initial speed of the ball as it leaves the jugglers hand is 10m/s
u = 10m/s
v = 0 (Since the ball will reach 0 velocity, once it reaches the maximum height possible and then will fall back again)
a = -g = -10m/s^2.
So, the time taken by ball to reach its maximum height
v = u+at
0 = 10-10t
t = 1 sec.
A)
V²=u²+2as. V= 0 - at the top = -u²=2×10×80. g=a=10m/s =U²=1600 U=40m/s V=u+at 0=40-10t. [ acceleration downwards is -ve] t=4s t=time of ascent Total time =8s Total ball =10 Interval kept between the ball will be 8/10=0.8s❤️❤️
