If the motorcycle can go from 0 to 50mph in 3 seconds the person is describing the motorcycle's acceleration.
The heavier object has a higher kinetic energy. Kinetic energy is the energy possessed by a body when in motion. It is given by 1/2 mv², where m is the mass and v is the velocity. At a constant velocity, increase in mass increases the kinetic energy. Therefore an object with heavier mass would have higher kinetic energy compared to the lighter energy.
Answers:
a) 198,55 s
b) 4687.98 m
Explanation:
a) Speed is defined as the variation of the position (distance traveled )of a body or object with time :
(1)
We are told the cheetah runs a distance of with a speed (Knowing and ), and we need to find the time it takes to travel that distance.
This means we have to find from (1):
(2)
(3)
(4)
b) Now, if we want to know the distance the cheetah will cover with in , we have to isolate from (1):
(5)
(6)
Finally:
answer is the color white
Answer:
Explanation:
Given that
Force between two masses
Where G is the constant
is the masses
d is the distance between masses.
To find the rate of change of force with distance d
