To calculate the average speed of the car, we need
B. The total distance driven on the racetrack
Explanation:
The average speed of an object in motion is given by
where
d is the distance covered by the object
t is the time interval considered to calculate the speed
The SI units of the speed are metres per second (m/s).
In this problem, we know the time interval:
t = 30 s
Therefore, in order to find the average speed, by looking at the equation we see that we also need the total distance driven by the car, so the correct answer is
B. The total distance driven on the racetrack

Answer:
Distance
Explanation:
distance is in vertical axis,or y-axis and time is on the horizontal axis,or x-axis.
Answer:
a = 4.9(1 - sinθ - 0.4cosθ)
Explanation:
Really not possible without a complete setup.
I will ASSUME that this an Atwood machine with two masses (m) connected by an ideal rope passing over an ideal pulley. One mass hangs freely and the other is on a slope of angle θ to the horizontal with coefficient of friction μ. Gravity is g
F = ma
mg - mgsinθ - μmgcosθ = (m + m)a
mg(1 - sinθ - μcosθ) = 2ma
½g(1 - sinθ - μcosθ) = a
maximum acceleration is about 2.94 m/s² when θ = 0
acceleration will be zero when θ is greater than about 46.4°
Answer:
Explanation:
We are given that
Charge=q=
Potential difference=V=3 V
We know that
Work done=
Using the formula
Work done by charge to move from the negative terminal to the positive terminal of battery=
J
Work done by charge to move from the negative terminal to the positive terminal of battery=
