Kinetic energy = 1/2 M V2
1/2 (80) V2 = 15,000
V2 = 15,000/40 = 375
V = sqrt(375) = 19.365 meters/sec
If the student is enrolled at the Sorbonne or McGill, the speedometer reads 69.7 km/hr.
If the student goes to MIT or Univ. of Rochester, the speedometer reads 43.3 mph .
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
The formula for kinetic energy is 1/2 x mass x speed squared. Just replace the mass and the velocity with the numbers. Since standard SI units are used, the answer will be in joules.
The bike's kinetic energy is 45 joules.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
It will decrease by a factor 9.
The graph is linear.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
Kinetic energy = 0.5 x mass x velocity^2. Your answer should be velocity.
the dump truck has the lowest kinetic the bike has the greatest becase of their mass
