Answer:
Launch velocity of the fleas = 1.80 m/s
Explanation:
Optimal launch angle is the angle that guarantees the maximum horizontal distance covered.
Optimum launch angle = 45°
The horizontal distance covered by a projectile is given as Range
R = (u² sin 2θ)/g
u = initial velocity of the projectile (flea) = ?
R = range = 33 cm = 0.33 m
θ = 45°
2θ = 2 × 45° = 90°
Sin 90° = 1
g = acceleration due to gravity = 9.8 m/s²
R = (u²/g)
u² = Rg = 0.33 × 9.8 = 3.234
u = 1.80 m/s
Hope this helps!!!
