Answer:
TRUE. The weight component is responsible for acceleration and therefore the increase in vehicle speed,
Step-by-step explanation:
Let's write Newton's second law for the car down a slope
Y Axis
N-Wy = 0
N = Wy
X axis
Wx -fr= m a
Using trigonometry
sin θ = Wx / W
cos θ = Wy / W
Wx = W sin θ
Wy = W cos θ
We replace
W sin θ - fr = m a
The weight component is responsible for acceleration and therefore the increase in vehicle speed,
fr is the force of car brakes
Consequently, of the above TRUTH
