Later in the game, the quarterback throws a pass to the wide receiver with a defender in hot pursuit. If the pass does not arrive to the wide receiver in two seconds, the pass will be intercepted. If the receiver is 30 yards away and the pass is thrown at a 10 degree angle from the ground, how fast must the ball be thrown to reach the receiver

Respuesta :

Answer:

Explanation:

In projectile motion , formula for range is as follows

R = u² sin 2 α / g , where u is initial velocity of throw , α is angle of throw

Given R , range = 30 yards , α = 10°

30 = u² sin 20 / 9.8

u² x .342 = 294

u² = 859.65

u = 29.32 m / s
