Mass = 20g = (20/100)kg = 0.02kg
Extension = 5cm = (5/100)m = 0.05m
K = 200N/
V = ?
1/2mv² = 1/2ke²
V = √ke²/m = √200×0.05×0.05/0.02
V = √25
V = 5m/s
===================================

P - Initial velocity of the projectile
B - Angle of projection
H - Maximum height reached by the projectile
R - Range or the total horizontal distance covered by the projectile
(2b)
R=P^2 sin 2β/g
at maximum range sin2β=1
