Answer:
it was thrown with the speed of 10m/s
Explanation:
u...?
v...0m/s
t...10s
g...-10m/s^2
using 1st equation of motion...
v=u+gt
0=u+(-10)(10)
0=u-100
100=u

Answer:
to go upward stone had taken time 5 sec
at the highest level the v = 0
u = ?
t = 5s
a = -10m/s² ( a is in opposite direction )
v = u + at
0 = u + ( -10×5)
-u = -50
u = 50 m/s
