Answer:
The answer to your question is C
Explanation:
acceleration is a vector quantity because it has both magnitude and direction
Answer:
d = 10.2 m
Explanation:
When the car travels up the inclined plane, its kinetic energy will be used to do the work in climbing up. So according to the law of conservation of energy, we can write that:

where,
m = mass of car
v = speed of car at the start of plane = (36 km/h)(1000 m/1 km)(1 h/3600 s)
v = 10 m/s
F = force on the car in direction of inclination = W Sin θ
W = weight of car = mg
θ = Angle of inclinition = 30°
d = distance covered up the ramp = ?
Therefore,

<u>d = 10.2 m</u>
With its apparent magnitude
Answer:
3 formula are
v = u + at
v² = u² + 2as
s = ut + ½at²
what is motion
the action or process of moving or being moved.
