Explanation:
Answer:
Looks like you have:
a = -.324 cos 2.5 t
In this case ω^2 A = .324
ω = 2.5
f = ω / (2 * pi) = 2.5 / 6.28 = .40 / sec

Answer:
Velocity of the car at the bottom of the slope: approximately
.
It would take approximately
for the car to travel from the top of the slope to the bottom.
Explanation:
The time of the travel needs to be found. Hence, make use of the SUVAT equation that does not include time.
- Let
denote the final velocity of the car. - Let
denote the initial velocity of the car. - Let
denote the acceleration of the car. - Let
denote the distance that this car travelled.
.
Given:
Rearrange the equation
and solve for
:
.
Calculate the time required for reaching this speed from
at
