Answer:
the only way to burn calories is to burn more calories than you consume
fat is very unhealthy to the body, and can cause serious issues
if you do not burn calories, they will turn into fat
eating the right amount of calories is healthy
buring fat can prevent health problems like heart disease

The acceleration of the car is 0.5 meters per seconds square.
Given the following data:
- Initial velocity, U = 30 m/s
Note: The final velocity (V) of the car would be zero (0) m/s when it comes to a stop.
To find the acceleration of the car, we would use the third equation of motion;
Mathematically, the third equation of motion is given by the formula;
<em>Acceleration, a </em><em>=</em><em> 0.5 </em><em></em>
Therefore, the acceleration of the car is 0.5 meters per seconds square.

Answer:
8 ms⁻¹
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = (1/2)mv²
So you get, for lorry,
K.E. = (1/2)4000×4² -----------(1)
for car,
K.E. = (1/2)1000×v²---------------(2)
(1)=(2)
(1/2)4000×4² = (1/2)1000×v²
y these two equations, we get, v = 8 ms⁻¹
The first force has magnitude 60 N and makes an angle of -30° relative to the positive horizontal axis (i.e. to the immediate right), while the second force has magnitude 150 N and direction +30° from the horizontal.
In component form, we have
The resultant force is the vector
Its magnitude is
Its direction is such that
Because the components of the resultant force are both positive, that means the angle makes with the horizontal is between 0° and 90°. So
