<span>At any particular time of day on June 23, sunlight will fall on the
northern hemisphere more directly than the southern hemisphere,
and on the north pole more directly than the south pole. (In fact,
at that time, the south pole will be halfway through a 6-month period
of no sunlight at all.)
On June 23, the sun will appear to be directly over the parallel
of 23.5</span>° north latitude<span>, or nearly so ... the farthest north that the
sun ever appears to be.</span>
Answer:
Time, t = 50.8 seconds.
Explanation:
Given the following data;
Mass = 6000 kg
Force = 2950 N
Initial velocity = 4 m/s
Final velocity = 29 m/s
To find time;
First of all, we would determine the acceleration of the truck using the following formula;
Force = mass * acceleration
2950 = 6000 * acceleration
Acceleration = 2950/6000
Acceleration = 0.492 m/s²
Next, we find time using the first equation of motion;
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
Making time, t the subject of formula, we have;
Substituting into the equation, we have;
Time, t = 50.8 seconds.
