Answer:
Newton's third law of motion.
Explanation:
We are told the force needed to throw the full soda can was more than that needed to throw the empty can.
Now, the weight of the full soda can will be more than that of the empty can. Therefore, the full can will demand more force than that of the empty can due to Newton's third law of motion which states that to every action, there is an equal and opposite reaction.
Answer:
c) 17 m
Explanation:
From the conservation of energy.
Change in kinetic energy= change in potential energy
Now,
Now according to the situation.
Here, v is the velocity, m is the mass of an object, h is the height, g is the acceleration due to gravity.
Given that the speed of the bicycle is
And the acceleration due to gravity is
Substitute these values.
Which means it is equivalent to 17 m
Therefore, the maximum height is 17 m
"with the wind" is a tail-wind, and the speeds are added to get the groundspeed.
"against the wind" is a head-wind, and the windspeed is subtracted from the airspeed.
Gravitational potential energy can be calculated using the formula <span>PE = m × g × h, where g is the gravitational acceleration and is constant hence the energy is dependent directly to mass and the height of the object. Hence more PE is registered when the object is heavier and/or at greater initial height. </span>
