Suppose a skydiver (mass = 75kg) is falling toward the Earth. When the skydiver is 100m above the earth he is moving 60m/s. At t
sleet_krkn [62]

Answer:

Kinetic energy  = 135 kJ

Potential energy = 73.5 kJ

Explanation:

 Mass of sky diver = 75 kg

  Velocity = 60 m/s

   Height = 100 m

 Kinetic energy is given by the expression, KE = \frac{1}{2} mv^2, where m is the mass and v is the velocity.

  So Kinetic energy  = \frac{1}{2} *75*60^2=135000J=135kJ

 Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.

 So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ

I need help with this fast! Thanks!

Answer: 8 1/20 or 8.05.

Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.

If g(x) = 3/2x + 3, and g(a) = 0, what is a ?
Lostsunrise [7]

Answer:

a = -2

Step-by-step explanation:

g(x) = 3/2x + 3

g(a) = 0

g(a) = 3/2a +3 =0

Subtract 3 from each side

3/2a +3-3=0-3

3/2a = -3

Multiply each side by 2/3

2/3 * 3/2a = -3*2/3

a = -2
