Answer:
5.00 x 10^9 j
Explanation:
mass = 100 kg
speed / velocity = 10 km/s x 1000 = 10,000m
K.E =
10,000x 100/ 2
= 5000000000
= 5.0 x 10^9j
At the bottom left,
Increasing potential energy.
At ascending,
Increasing kinetic energy.
At the peak,
Greatest potential energy.
At the descending,
Greatest kinetic energy.
Answer:
The vehicle travels 56.25 metres in the interval during which body decelerates .
Explanation:
- Initial velocity of vehicle, u = 32 m/s
- Final velocity of vehicle, v = 22 m/s
- Rate of acceleration, a = - 4.8 m/
Let the distance travelled be s .
We have to determine the distance travelled by the vehicle during this time.
The equation of motion is given by
s =
<u>s = 56.25 metres</u>
The vehicle travels 56.25 metres in the interval during which body decelerates .

Explanation:
Force may be defined as the cause of motion and deformation. When a force is applied to an object, the object either moves or changes shape or both. In most cases, it is not possible to detect the deformation by naked eyes at the molecular or atomic level. Deformation occurs no matter how small.
For example, a car moving along a straight and horizontal highway, experiences an engine force Fe, while being opposed by an overall frictional force, Ff ( road friction as well as air resistance). If the car is moving to the right and to the right is taken to be the positive direction, then Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe - Ff .
