A mass weighing 16 pounds stretches a spring 8 3 feet. The mass is initially released from rest from a point 6 feet below the eq

uilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1 2 the instantaneous velocity. Find the equation of motion x(t) if the mass is driven by an external force equal to f(t)

How far will a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal and wit
Elis [28]

Explanation:

It is given that, a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal.

Speed with which it is thrown, v = 11 m/s

We need to find the maximum height above the ground level. The maximum height attained by the stone is given by :

h=\dfrac{v^2sin^2\theta}{2g}

h=\dfrac{(11\ m/s)^2sin^2(30)}{2\times 9.8\ m/s^2}

h = 1.54 m

So, the stone will travel a distance of 1.54 meters.

Range of a projectile is given by :

R=\dfrac{v^2sin\ 2\theta}{g}

R=\dfrac{(11\ m/s)^2sin(60)}{9.8\ m/s^2}

R = 10.69 m

So, the maximum range achieved with the same initial speed is 10.69 meters. Hence, this is the required solution.

Which scientist first discovered the white light is a mixture of a rainbow spectrum of light rays
gavmur [86]

Issac Newton

In the 17th century, Isaac Newton discovered that prisms could disassemble and reassemble white light, and described the phenomenon in his book Opticks. He was the first to use the word spectrum (Latin for "appearance" or "apparition") in this sense in print in 1671 in describing his experiments in optics.
