Kinetic energy is _____.inversely proportional to mass and velocity directly proportional to mass and velocity directly proporti
2 answers:
Answer : The correct option is, directly proportional to mass and velocity.
Explanation:
Kinetic energy : It is associated with the state of motion of an object.
The formula used for kinetic energy is,
where,
m = mass of an object
v = velocity or speed of an object
From the formula of kinetic energy we conclude that,
The kinetic energy is directly proportional to the mass and the velocity of an object.
Hence, the kinetic energy is directly proportional to mass and velocity.

Answer:
# of Snickers bars 2
Explanation:
Power output= 0.30 HP
=0.3*746
= 0.30 HP (746 W=1.00 HP)
= 224 W
time required 2 h 49 m = 10140 seconds
Since power is work divided by time, then work is:
Work done by the jet = P*t
= 224 *(10140)
= 2.3 MJ (2.3 x J)
Converting MJ to Cal
2.3 MJ=549 Cal
# of Snickers bars = 549 Cal / 280 Cal
= 2.0 bars (rounded from 1.96)
