Answer : Height, h = 20.4 m

Explanation :

It is given that,

Mass of an object, m = 500 g = 0.5 kg

Gravitational potential energy, PE = 100 J

The Gravitational potential energy is the energy which is possessed due to the height and gravity of an object. It is given as :

PE = m g h

where,

h is the height of the cliff.

100\ J=0.5\ kg\times 9.8\ m/s^2\times h

h = 20.40 m

So, the height of the cliff is 20.4 m.

A car with a velocity of 22 m/s is accelerated at a rate of 1.6m/s2 for 6.8s. determine the final velocity
Ivahew [28]

A car with a velocity of 22 m/s is accelerated at a rate of 1.6 m/s^2 for 6.8s has the final velocity t be 32.88 m/s.

The acceleration means the amount of velocity changing per unit time.

The given data:

initial velocity, u = 22 m/s

time, t = 6.8 s

acceleration, a = 1.6 m/s^2

We will be using the equation of motion:

v = u + at

\therefore v=22+1.(6.8)

\Rightarrow v=22+10.88

\Rightarrow v=32.88 \ m/s

The final velocity become 32.88 m/s.

Can I get help and an explanation on C?
Diano4ka-milaya [45]

Answer:

1.67 m/s

Explanation:

Momentum is conserved.

Initial momentum = final momentum

(30 kg) (10 m/s) + (35 kg) (-10 m/s) = (30 kg) v + (35 kg) (0 m/s)

300 - 350 = 30v

v = -5/3 m/s

Linus will move at 1.67 m/s in the direction opposite that he started.

Using Kepler's 3rd law and Newton's law of universal gravitation, find the period of revolution P of the planet as it moves arou
weeeeeb [17]

Answer:

P =  \pi \sqrt{\frac{(R_1+R_2)^3}{2 \ GMS}}

Explanation:

From the attached diagram below:

AC = a (1 + e) = R₂     -------- equation (1)

CD = a ( 1 - e) = R₁     ---------   equation (2)

⇒ 1 - e = \frac{R_1}{a}

e= 1 - \frac{R_1}{a}

Replacing the value for e into equation (1)

a(1+1- \frac{R_1}{a})= R_2

= 2a - R_1 = R_2

a= \frac{R_1+R_2}{2}

From Kepler's third law;

P = 2 \pi \sqrt{\frac{a^3}{GMS}}

P = 2 \pi \sqrt{\frac{(R_1+R_2)^3}{8GMS}}

P =  \pi \sqrt{\frac{(R_1+R_2)^3}{2 \ GMS}}
