<span>Action force is force acting in one direction. Reaction force is force acting in the opposite direction. Learn more about Newton's Third Law as it explains action and reaction forces through several examples, and test your knowledge with quiz questions.

Hope this help! And if you can, can you put me down for brainliest, please?

A 50 kg bobsled slides down an ice track starting (at zero initial speed) from the top of a(n) 184 m high hill. The acceleration

Feliz [49]

Answer:

Explanation:

Given

mass of ice $m=50\ kg$

Height of hill $h=184\ m$

Neglecting air resistance

As resistance is absent so Energy at top of hill and at the bottom hill is conserved.

Energy at top is equal to Potential Energy

$E_T=mgh=50\times 9.8\times 184$

Energy at bottom is equal to kinetic energy at bottom

$E_B=\frac{1}{2}mv^2$

$E_T=E_B$

$50\times 9.8\times 184=\frac{1}{2}\times 50\times v^2$

$v=\sqrt{2\times 9.8\times 184}$

$v=60.05\ m/s$

Answer:

gs = 0.6 m/s^2

Explanation:

Given data:

velocity = 12 m/s

height s = 12t -(1/2) g_s t^2

Given velocity is the derivatives of height

$v(t) = \frac{d}{dt} s(t)$

$= \frac{d}{dt}(12t -\frac{1}{2} g_s t^2)$

$= 12 - g_s t$

when velocity tend to 0 , maximum height is reached

$v(t) = 12 - g_s t$

$0 = 12 - g_s t$

$g_s = \frac{12}{t}$

at t = 20 sec ball reached the max height, so

$g_s = \frac{12}{20} = 0.6 m/s^2$

The Punnett square is a square diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
