Aleonysh [2.5K]

Answer:

237.87 m/s

Step-by-step explanation:

This is a projectile question.

We use the equation for the range of a projectile since we are given the horizontal distance and angle of projection.

So, R = U²sin2θ/g where R = range, U = initial speed of rocket, θ = projection angle and g = acceleration due to gravity = 9.8 m/s².

Since it is given that the water body is 5 km away, R = 5 km = 5000 m and θ = 30°

So, making U subject of the formula, we have that

U = √(gR/sin2θ)

So, substituting the values of the variables, we have

U = √[9.8 m/s² × 5000 m/sin(2 × 30°)]

U = √[49000 m²/s²/sin60°]

U = √[49000 m²/s²/0.8660]

U = √[56,580.33 m²/s²]

U = 237.87 m/s

So the minimum speed of the rocket necessary to make sure the rocket reaches the water surface is U = 237.87 m/s

How do you find the Pythagorean Theorem?

wolverine [178]

Answer:

a^2 + b^2 = c^2

Step-by-step explanation:

Pythagorean's theorem is found using certain assumptions

Draw a square and make out four aright angles inside of it.

Label each side as 'a' 'b'. 'c'.

Where a is the opposite

b is the adjacent

c is the Hypotenuse.
