Answer:

m=22 kg

Explanation:

f=88

a=4

m=f/a

m=88/4

m=22

You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is negligible friction between
Tatiana [17]

Explanation:

Given that,

Mass of ball, m = 0.425 kg

Initial speed of the ball, u = 12 m/s

Initial speed of a person, u' = 0

Mass of a person, m' = 68 kg

(a) Let V is the combined speed of the person and the ball. Using conservation of momentum as :

mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{0.425\times 12+0}{(0.425+68)}\\\\V=0.0745\ m/s

(b) If the ball hits the person and bounces off his chest, so afterwards it is moving horizontally at 9.00 m/s in the opposite direction,. Let v' is the speed of the person after the collision. So,

mu+m'u'=mv+m'v'

v = -9 m/s

mu=mv+m'v'\\\\v'=\dfrac{m(u-v)}{m'}\\\\v'=\dfrac{0.427\times (12-(-9))}{68}\\\\v'=0.131\ m/s

Hence, this is the required solution.

Lauryn serves a volleyball with a mass of 2.1 kg. The ball leaves her hand with a speed of 30 m/s.
Naya [18.7K]

Hi! Let's see.

<h3><u>TOPIC: Kinetic Energy.</u></h3>

Explanation:

Data:

  • Mass(m) = 2.1 kilograms
  • Speed(v) = 30 m/s
  • Kinetic Energy(Ek) = ?

==================================================================

Use the kinetic energy formula:

  • \boxed{\boxed{\bold{E_{k}=\frac{m*(v)^{2}}{2}}}}

Replace by the data:

  • \boxed{E_{k}=\frac{2.1kg*(30\frac{m}{s})^{2}}{2}}}}}

We multiply speed squared:

  • \boxed{E_{k}=\frac{2.1kg*900\frac{m}{s}}{2}}}

Multiply in the numerator, without forgetting the units:

  • \boxed{E_{k}=\frac{1890J}{2}}}}

Both numerator and denominador operations are divided:

  • \boxed{\bold{E_{k}=945\ J}}

Answer: The kinetic energy is <u>945 Joules.</u>

What is the wavelength of a wave that travels at a speed of 3.0x10^8 m/s and has a frequency of 1.5x10^16 m/s?
Vlad [161]
Speed of wave = wavelength * frequency

Therefore, wavelength is 2.0 x 10^-8
