An object is dropped from rest from a height of 4.4 107 m above the surface of the Earth. If there is no air resistance, what is

kondaur [170]

Answer:

Explanation:

An object is drop from a height, then it is in direction of gravity

g is +ve

When an object drop from a height, the initial velocity is 0,

U=0

Given that h=4.4×10^7m

V=?

g=9.81m/s^2

Then using equation of motion

V^2=U^2+2gh

V^2=0+2×9.81×4.4×10^7

V^2=86.33×10^7m/s

Take square root of both side

V=29381.63m/s

Now to km/s, divide by 1000

Since 1km=1000m

V=29.38km/s

A 620 kg car is traveling at 24 m/s on horizontal ground when it starts up a 30 m high hill. The engine can produce up to 144,00

sweet-ann [11.9K]

Answer:

The kinetic energy of the car at the top of the hill is 140280 Joules.

Explanation:

Mass of the car, m = 620 kg

Speed of the car, v = 24 m/s

Height of the hill, h = 30 m

The engine can produce up to 144,000 J of work during that time, W = 144,000 J

We need to find the kinetic energy of the car at the top of the hill. It can be calculated using conservation of mechanical energy as :

$(mgh+K)-\dfrac{1}{2}mv^2=144000$

$(620\times 9.8\times 30+K)-\dfrac{1}{2}\times 620\times (24)^2=144000$

$620\times9.8\times30+K=322560$

$K=140280\ J$

So, the kinetic energy of the car at the top of the hill is 140280 Joules. Hence, this is the required solution.
