An object increases vert its velocity from 22M/S 236M/S and five seconds. What is the acceleration of the object
MariettaO [177]

Answer:

\boxed {\boxed {\sf a=42.8 \ m/s^2}}

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

a=\frac{v-u}{t} (<em>v </em>is the final velocity, <em>u</em> is the initial velocity, <em>t </em>is the time).

The velocity increased from 22 m/s to 236 m/s in 5 seconds. Therefore:

v=236 \ m/s\\u=22 \ m/s\\t= 5 \ s

Substitute the values into the formula.

a=\frac{236 \ m/s - 22 \ m/s}{5 \ s}

Subtract in the numerator.

  • 236 m/s-22 m/s=214 m/s

a=\frac{214 \ m/s}{5 \ s}

Divide.

a=42.8 \ m/s^2

The acceleration of the object is <u>42.8 meters per square second.</u>

What is the frequency of a photon with an energy of 4. 56 x 10^-19 j
Sauron [17]

The frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.

<h3>What is a frequency?</h3>

The number of waves that travel through a particular point in a given length of time is described by frequency. So, if a wave takes half a second to pass, the frequency is 2 per second.

Given that the energy of the photon is 4.56 x 10⁻¹⁹ J. Therefore, the frequency of the photon can be written as,

\rm \gamma = \dfrac{E}{h} = \dfrac{4.56x10^{-19} J}{6.626 \times 10^{-34}\ Jsec^{-1}}\\\\\\\gamma  = 6.88 \times 10^{14}\ s^{-1}

Hence, the frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.

A 75Kg man jumps from a window 1.0m above the sidewalk. If the man falls with his knees and ankles locked, the only cushion for
liq [111]

Answer:

150153.06122 N

Explanation:

m = Mass of person = 75 kg

h = Height of fall = 1 m

g = Acceleration due to gravity = 9.81 m/s²

F = Force

s = Displacement = 0.49 cm

Potential energy is given by

P=mgh\\\Rightarrow P=75\times 9.81\times 1\\\Rightarrow P=735.75\ J

Work is given by

W=Fs\\\Rightarrow F=\frac{W}{s}\\\Rightarrow F=\frac{735.75}{0.0049}\\\Rightarrow F=150153.06122\ N

The average force exerted is 150153.06122 N
