Given:-
To Find:-
Solution:-
Using 3rd Equation of Motion
❒ v² = u² +2gh
where
v is the final velocity
g is the acceleration
u is the initial velocity
h is the height
Substitute the value we get
→ 0² = u² + 2×(-10) × 30
→ 0 = u² + (-20)×30
→ -u² = -600
→ u² = 600
→ u =√600
→ u = 24.50 m/s
Therefore, the object was thrown upward as the speed of 24.50 m/s.

To Find :-
Formula Used :-
where,
Solution :-
Given :
According to the question by using the formula we get,
⇒ (0)² = (u)² + 2(10)(30)
⇒ 0 = u² + 2(300)
⇒ u² = 600
⇒ u =
➠ u = 24.50 m/s
The velocity with which it was thrown upwards is 24.50 m/s .
