use formula or Frist equation of motion

g = - 10 m/ s
u = 10 m/s
v = 0
distance = 10 m
FROM 1st equation of motion
v = u + at
0= 100 + ( -10 ) t
-100 = -10t
-100 / -10 = t
t = 10secs
u = 10 m/s
v = 0
distance = 10 m
FROM 1st equation of motion
v = u + at
0= 100 + ( -10 ) t
-100 = -10t
-100 / -10 = t
t = 10secs
