Two projectiles are launched from the ground simultaneously with an initial velocity 5.00 m/s. The first projectile is sent off at an angle of 10º with respect to the horizontal, and the second projectile at an angle of 80º. Which projectile lands on the ground in a region between 0.80 m and 1.00 m from the launcher? a) Neither
b) Frst projectile
c) Second projectile
d) Both projectiles

Respuesta :

Answer:d)Both

Explanation:

Given

Projected velocity (u)=5 m/s

First Projectile angle[tex](\theta _1)=10^{\circ}[/tex]

Second Projectile angle[tex](\theta _2)=80^{\circ}[/tex]

Range is given by [tex]R=\frac{u^2sin2\theta }{g}[/tex]

[tex]R_1=\frac{5^2sin20}{9.81}=0.871 m[/tex]

[tex]R_2=\frac{5^2sin160}{9.81}=0.871 m[/tex]

Range of both projectiles are same as they launched at complementary angles.
