Question

Please help answer this problem:
From the ground a projectile is fired with a velocity of 30m/s at 30 degrees above the horizontal and it takes 3.06 s toreturn to the ground. Find the range (horizontal distance)where the projectile returns to the ground.
R = __________
From the ground a projectile is fired with a velocity of 30m/s at 30 degrees above the horizontal and it takes 3.06 s toreturn to the ground. Find the range (horizontal distance)where the projectile returns to the ground.
R = __________

Explanation / Answer

Given that the initial velocity is u = 30 m/s angle is = 30o Time taken is t = 3.06 s ------------------------------------------- The range of projectile is R = horizontal velocity * time offlight                                           = (u cos) *t                                          = 79.50 m
