A gun has a muzzle speed of 150 m/s. Find two angles of elevation that can be used to hit a target 800m away.

lorasvet [3.4K]

Answer:

Explanation:

u = 150 m/s

R = 800 m

The formula for the horizontal range is

$R=\frac{u^{2}Sin2\theta }{g}$

where, θ is angle of projection.

$800=\frac{150^{2}Sin2\theta }{9.8}$

Sin2θ = 0.348

2θ = 20.4°

θ = 10.2°

The range is same for the complementary angles.

So, the other angle is 90 - 10.2 = 79.8°

Explanation:

KE= ?

m= 75 kg

v= 35 m/s

KE= 1/2 (75)(35)^2

KE= (37.5)(17.5)

KE= 656.25 J
