The range of a projectile fired at an angle with the horizontal and with an initial velocity of feet per second is where r is me
77julia77 [94]

Answer:

θ = 8.50°

To the nearest angle

θ = 9.0°

the golfer must hit the ball at angle 9° so that it travels 120 feet.

Explanation:

The range of a projectile is the horizontal distance covered by a projectile, which can be written as;

r = (u^2× sin2θ)/g

Where;

r = range

u = initial speed

θ = angle from horizontal

g = acceleration due to gravity

Solving for θ,

sin2θ = rg/u^2

θ = 1/2 × sin⁻¹(rg/u^2) ....1

Given;

r = 120 ft

u = 115 ft/s

g = 9.81m/s = 32.2 ft/s

Substituting the values into the equation 1;

θ = 1/2 × sin⁻¹(120×32.2/115^2)

θ = 1/2 × sin⁻¹(0.29217)

θ = 1/2 × 17.00

θ = 8.50°

To the nearest angle

θ = 9.0°

Two objects of the same mass are on two different planets. Planet A has a force of gravity that is weaker than that of planet B.
iris [78.8K]
C) The weight of the object on planet A will be less than the weight of the object on planet B.


This happened because: when gravitational pull of a planet is weak, an object will weigh less as a result of less gravity forcing it down to the ground.

Water has a specific heat of 4.186 J/g°C. How much heat is required to increase 10.0 g of water from 25.0°C to 30.0°C?
poizon [28]

Answer:

=0.2093J

Explanation:

Heat required(Q) = mcø

= (10/1000)*4.186*(30-25)

= 0.2093J
