Answer:
The actual output voltage produced is 4.8 V
Explanation:
given information:
R₁ = 4.7k Ω
R₂ = 10k Ω
V =15 V
nominal output = 5 V
actual output voltage produce :
V₀ = (R₁/(R₁+R₂))V
= (4.7/(4.7+10)) (15)
= (4.7/14.7) (15)
= 4.8 V
The car travels at a speed of 25m/s.
<u>Explanation:</u>
Given-
Mass, m = 1500kg
Coefficient of friction, μk = 0.47
Distance, x = 68m
Speed, s = ?
We know,
and
F = μ X m X g
Therefore,
μ * m * g = m * a
μ * g = a
Let, g = 9.8m/s²
So,
We know,
where, v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
If the car comes to rest, the final velocity, v becomes 0.
So,
The car travels at a speed of 25m/s.
