The roller coaster has a mass of 600 Kg speeds up to 22 m/s as it goes down a giant hill. Calculate the kinetic energy. SHOW WORK!

Respuesta :

Answer:

  • 145.2 kJ

Step-by-step explanation:

Kinetic Energy formula

  • K.E. = 1/2mv², where :
  1. m = mass
  2. v = velocity

Substituting the given values

  • K.E. = 1/2 x 600 x (22)²
  • K.E. = 300 x 484
  • K.E. = 145200 J
  • K.E. = 145.2 kJ

Answer:

145,200 J

Step-by-step explanation:

  • The formula to calculate kinetic energy is [tex]K=\frac{1}{2}mv^{2}[/tex], where K is the kinetic energy in Joules, m is the mass in kg, and v is the velocity in m/s
  • Substitute in the values
  • [tex]K=\frac{1}{2}\times 600\times 22^{2}[/tex]
  • [tex]K=\frac{1}{2}\times 600\times 484[/tex]
  • [tex]K=\frac{1}{2}\times 290400[/tex]
  • [tex]K=145200[/tex]
