A placekicker kicks a football upward at an angle of 30 and a speed of 5.0 m/s at what other angle will he have to kick a second

Flura [38]

Answer: $60^{\circ}$

Explanation:

Given

speed of ball $u=5 m/s$

launch angle $\theta =30^{\circ}$

Range of a Projectile $R=\frac{u^2\sin 2\theta }{g}$

Range will be common for two angles i.e. $\theta [tex] and [tex]90-\theta$

for $\theta R=\frac{5^2\sin 2\cdot 30}{g}$

$R=2.209 m$

For $90-\theta$

$90-30=60^{\circ}$

$R=\frac{5^2\sin 2\cdot 60}{g}$

$R=2.209 m$

Answer:

The correct option is 1. 720 m

Explanation:

Projectile Motion

When an object is launched in free air (no friction) with an initial speed vo at an angle $\theta$ , it describes a curve which has two components: one in the horizontal direction and the other in the vertical direction. The data provided gives us the initial conditions of the survival package's launch.
