11.4 Kinetic energy
... J. Assume for the sake of simplicity that Jupiter was at rest. . Since we assume Jupiter was at rest, we can imagine that the comet stopped completely on impact, and 100% of its kinetic energy was converted to heat and sound. We first convert the speed to mks units, v = 6 × 104 m/s, and then plug in ...

... Equation 6.9 says that the force of the atmosphere upon the cart is negligible. We are neglecting drag along the direction of motion of the cart. In reality, the frictional drag of the air upon the cart may be a significant source of error. However, we really have no way of determining whether the f ...

Because the object initially travels downward, it will be three-fourths of the way through its cycle when it first reaches its maximum height. We can find the minimum initial speed the object would need to be given in order for th ...
