# Determine the flight range of a ball thrown from the ground at an angle of 30 ° to the horizon, if the flight time was 6 s.

December 29, 2020 | education

| The total time of movement when moving at an angle to the horizon is:

t = 2V * sin a / g = V / g

Hence, V = t * g

Range L:

L = V ^ 2 * sin2a / g = t ^ 2 * g ^ 2 * sin 60 / g = t ^ 2 * g * sqrt (3) /2=36*10*0.85=360*0.85=288+18= 306m

Answer: L = 306m
