Physics

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

In a football game, a 90 kg receiver leaps straight up in the air to catch the 0.42 kg ball the quarterback threw to him at a vi
irinina [24]

To solve this problem it is necessary to apply the equations related to the conservation of momentum. Mathematically this can be expressed as

m_1v_1+m_2v_2 = (m_1+m_2)v_f

Where,

m_{1,2}= Mass of each object

v_{1,2} = Initial velocity of each object

v_f= Final Velocity

Since the receiver's body is static for the initial velocity we have that the equation would become

m_2v_2 = (m_1+m_2)v_f

(0.42)(21) = (90+0.42)v_f

v_f = 0.0975m/s

Therefore the velocity right after catching the ball is 0.0975m/s

Pitch, roll, and yaw are all terms for specific kinds of motion. What does pitch mean?\
ad-work [718]
All these terms are related to an aircraft system. A pitch is a rotational motion around the side-to-side axis. It is a phenomenon when a plane is tilted upwards to increase lift of the tail or tilted downwards to decrease it. It is controlled by an elevator from the pilot maneuvering system.

What Is the definition of the term gravitational potential energy​
OLga [1]

Answer:

Here are all the possible meanings and translations of the word gravitational energy. Gravitational energy is the potential energy associated with the gravitational field. This phrase is found frequently in scientific writings about quasars and other active galaxies. Quasars generate and emit their energy from a very small region.

A projectile's horizontal range on level ground is r=v20sin2θ/g. at what launch angle or angles will the projectile land at half
Ksju [112]

As given the formula of range is

R = \frac{v^2sin2\theta}{g}

now for the maximum range

\theta = 45

R_{max} = \frac{v^2}{g}

now for half of this maximum range we will have

\frac{R_{max}}{2} = \frac{v^2sin2\theta}{g}

\frac{v^2}{2g} = \frac{v^2sin2\theta}{g}

now from above we have

sin2\theta = \frac{1}{2}

so two possible values for above is given as

\theta = 15 degree, 75 degree

so above two angle we will have half of maximum range
