A bus travels from el Paso, texas, to chihuahua, mexico, in 5 hr with an average velocity if 75km/hr to the south. How far is Ch
1 answer:
375km
Explanation:
Given parameters:
Time of travel = 5hr
Average velocity = 75km/hr south
Unknown:
Displacement between Chihuahua and El paso = ?
Solution:
Velocity is the rate of change of displacement of a body with time. It is a vector quantity that has both magnitude and direction;
Velocity =
Since the unknown is displacement;
displacement = velocity x time
input the values;
displacement = 75km/hr x 5hr = 375km

Answer:
Approximately (assuming that the projectile was launched at angle of
above the horizon.)
Explanation:
Initial vertical component of velocity:
.
The question assumed that there is no drag on this projectile. Additionally, the altitude of this projectile just before landing is the same as the altitude
at which this projectile was launched:
.
Hence, the initial vertical velocity of this projectile would be the exact opposite of the vertical velocity of this projectile right before landing. Since the initial vertical velocity is (upwards,) the vertical velocity right before landing would be
(downwards.) The change in vertical velocity is:
.
Since there is no drag on this projectile, the vertical acceleration of this projectile would be . In other words,
.
Hence, the time it takes to achieve a (vertical) velocity change of would be:
.
Hence, this projectile would be in the air for approximately .
