Arisa [49]3 years ago
4 0

Explanation:

Distance = (intial speed)X(Time) + 1/2(acceleration)X(Time) [Third equation of motion]

As initial speed is zero, therefore;

Distance = 1/2(acceleration)X(Time)

              = 1/2 (6 X 15)

              = 1/2 (90)

              = 45 meters

Hence, the object traveled 45 meters.

kotegsom [21]

Answer:

The take-off speed is 41.48 \frac{m}{s}

Explanation:

Given :

Range R = 77 m

Projectile angle \alpha  = 13°

From the formula of range,

  R = \frac{v_{o} ^{2}   }{g} \sin 2\alpha

Find the velocity from above equation,

  v_{o} = \sqrt{\frac{gR}{\sin 2 \alpha } }

  v_{o} = \sqrt{\frac{9.8 \times 77}{\sin 26} }                              ( ∵ g = 9.8 \frac{m}{s^{2} } )

  v_{o} = 41.48 \frac{m}{s}

Therefore, the take-off speed is 41.48 \frac{m}{s}

A measurement that has both magnitude and direction
Korvikt [17]
<span>A measurement that both magnitude and direction is a vector quantity. An example of this is a moving car. The car exerts force due to its thrust and weight that runs in it. This will give us the magnitude of the car. The resulting motion of the car in terms of displacement, velocity and acceleration that determines its direction makes it a vector quantity. On the other hand, a measurement that has only magnitude is a scalar quantity. The energy exerted by the engine of the car is a scalar quantity.</span>
