A ball is thrown vertically upwards. It returns6 s later. Calculate :

1.	A ball is thrown vertically upwards. It returns6 s later. Calculate : fit the greatest height reachedby the ball, and if the initial velocity of the ball,(Take g = 10 m s^)
Answer» TIME taken for maximum height=6/2=3s we KNOW v=u+at 0=u+ (-10)3 u=30m/s and $s = ut + 1 \div 2at {}^{2} \\ \: \: = \: 30 \times 3 + 1 \div 2 \times 10 \times 3 \\ \: \: \: = 105m$ I hope it is helpful for u

Answer»

TIME taken for maximum height=6/2=3s

we KNOW

v=u+at

0=u+ (-10)3

u=30m/s

and

$s = ut + 1 \div 2at {}^{2} \\ \: \: = \: 30 \times 3 + 1 \div 2 \times 10 \times 3 \\ \: \: \: = 105m$

I hope it is helpful for u
