Here as we know that there is no loss of energy
so we can say that maximum kinetic energy will become gravitational potential energy at its maximum height
So here we have

here we have
v = 20 m/s
m = 8000 kg
now from above equation we have



so maximum height is 20.4 m
Frequency = 1/time period = 1/0.05 = 20s^-1.
Answer:
this vehichle has 896,000 jules of energy
Explanation: KE=1/2mv squared, KE is Kinetic energy. m is mass and v is velocity
Maybe you can divide the volts its twelve if you do that but itll show you how much to double it by
The answer would be the sound waves.
