Kinetic energy than parked
When the truck accelerates forward the ball will shift to the back of the bed of the truck because of inertia
Answer:
7.0 m
Explanation:
Step 1: Given data
Initial speed of the ball (u): 1.8 m/s
Acceleration (a): 6.1 m/s²
Final speed of the ball (v): 9.4 m/s
Step 2: Calculate the displacement (s) of the ball
The ball is moving with a uniformly accelerated rectilinear motion. We can calculate the displacement using the following suvat equation.
v² = u² + 2 × a × s
s = (v² - u²)/2 × a
s = [(9.4 m/s)² - (1.8 m/s)²]/2 × 6.1 m/s²
s = 7.0 m
Answer:
Temperature is the kinetic energy of the particles of a substance.
Explanation:
The more kinetic energy a particle has the higher it's temperature. In the case of the atmosphere, which is what we are primarily concerned with in Meteorology, we measure this using a mercury thermometer (in certain situations we use an alcohol thermometer and of course modern times have given us things like dewcells and digital thermometers but we always go back to the mercury thermometer for accuracy).
No, gravity does not have mass, it behaves like a particle without mass
