A 1.40-kg block is on a frictionless, 30 ∘ inclined plane. The block is attached to a spring (k = 40.0 N/m ) that is fixed to a

wall at the bottom of the incline. A light string attached to the block runs over a frictionless pulley to a 60.0-g suspended mass. The suspended mass is given an initial downward speed of 1.60 m/s .
How far does it drop before coming to rest? (Assume the spring is unlimited in how far it can stretch.)
Express your answer using two significant figures.

a ball was kicked horizontally off a clif at 15m/s, how high was the cliff if the ball landed 83 m from base of the cliff
lana [24]

The ball's horizontal position x at time t is

x=v_{0x}t

The ball has initial velocity in the horizontal direction only, so v_{0x}=15\,\frac{\mathrm m}{\mathrm s}. Then the time it takes for the ball to travel 83 m horizontally t is given by

83\,\mathrm m=\left(15\,\dfrac{\mathrm m}{\mathrm s}\right)t\implies t=5.5\,\mathrm s

Meanwhile, the ball's vertical position y at time t, starting at the height of the cliff h, is given by

y=h-\dfrac12gt^2

where g=9.8\,\frac{\mathrm m}{\mathrm s^2} is the acceleration due to gravity. After 5.5 seconds, the ball hits the ground, so that y=0 when t=5.5\,\mathrm s, and we use this to solve for h:

0=h-\dfrac12g(5.5\,\mathrm s)^2\implies h\approx150\,\mathrm m

Imagine you are mpho:how can you help your friend (phenyo) not to be influenced by media? you really feel she needs some help be
LUCKY_DIMON [66]

One of the ways to help someone not to be influenced by media is:

  • Encourage independent thinking.
  • Let her know that she should make sure the information she is consuming is free from bias and is factual.

<h3>What is Media Influence?</h3>

This refers to the effects and reactions which the mass media has on the people who listen to them by shaping their views and by controlling the narrative.

With this in mind, we can note that if a person is overtly influenced by the media, then such a person lacks independent thinking and becomes emotional by what he watches on the television or reads from an online source.

This can be changed through the encouragement of independent thinking, and the need to check for factual information from the media news and also to focus more on studies.

The magnitude of a vector can be different in different coordinate systems. The magnitude of a vector can be different in differ
Georgia [21]

Answer:

False.

Explanation:

We usually define vectors in terms of its magnitude and their orientation. Magnitude and direction does not vary with the change of a coordinate system as they are independent of coordinates and will remain the same. So it does not matter what your choice of a coordinate system is, it will not effect its direction and magnitude. However you can resolve the vector in to its components if you want.
