Calculate the total energy of 2.0 kg object moving horizontally at 10 m/s 50meters above the surface. 1080 J
2 00 J
1 00 J
10. J

1080J

Explanation:

Given parameters:

Mass of object  = 2kg

Velocity  = 10m/s

Height  = 50m

Unknown:

Total energy  = ?

Solution:

The total energy of the moving object is obtainable by summing the kinetic and potential energy;

       Total energy  = P.E + K.E

P.E is the potential energy  = mgh

K.E is the kinetic energy = mv²

 Now insert the parameters and solve;

    Total energy  = mgh +  mv²

m is the mass

g is the acceleration due to gravity

h is the height

v is the velocity

  Total energy  = (2 x 9.8 x 50) +  ( x 2 x 10²)

  Total energy  = 980 + 100 = 1080J

true

explanation:

i had this question and the answer was 3.15 miles.
