Orlov [11]4 years ago
6 0

Answer:

we know that

ke=1÷2×mv^2

and when speed become triple of original then new speed become 3v

then,new ke=1÷2×m(3v)^2

=1÷2×9mv^2

9×original ke

hence ke will increase by 9 times

A helicopter, initially hovering 40 feet above the ground, begins to gain altitude at a rate of 21 feet per second. Which of the
Montano1993 [528]

Answer: y = 40 + 21t

Explanation:

Apply the equation of distance covered.

d = vt + C

Where d is the distance covered

v = velocity , t = time

C = constant = initial distance covered

For the case above....

d = y

y(t) = vt + C

But y(0) =40 = C

C = 40ft

velocity v = 21 ft/s

Therefore, the equation of the altitude is given by;

y(t) = 21t +40

y = 40 + 21t

Venus has an average distance to the sun of 0.723 AU. In two or more complete sentences, explain how to calculate the orbital pe
vodka [1.7K]
 We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s. 
    An average distance to the Sun ( In kilometers ) is:
    R = 0.723 * 149,579,871 km= 108,150,260 km.
    Than we will calculate the orbital period ( T ).
    v = 2 π R / T
    T = 2 π R / v
    T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
    T = 5389.75 s ≈ <span>224.5 days
    The orbital period of Venus is approximately 224.5 days.</span>

An object of mass 82kg is accelerated upward at 3.2m/s/s. what force is required
vampirchik [111]

F = m · a

In order to accelerate 82 kg upward at the rate of 3.2 m/s², a NET upward force of (82kg · 3.2m/s²) =  262.4 Newtons is required.

But if the object is on or near the surface of the Earth, then there's a downward force of (82kg · 9.8m/s²) = 803.6 N already acting on it because of gravity.

So you need to apply (803.6N + 262.4N) = <em>1,066 Newtons UPward</em>, in order to cancel its own weight and accelerate it upward at that rate.
