It would be balanced. (No acceleration - No change in motion)
Answer:
Explanation:
The initial velocity, u, of the car=15m/s
The final velocity, v, of the car =0m/s
Time, t, taken for the car to come to a stop=5s
Acceleration is calculated by,
By substitution,
The negative sign implies that the car has decelerated.
First, use a high-quality measurement tool. Next, measure carefully. Finally, repeat the measurement a few times. Hope it helps!
Explanation:
The motion of a particle is defined by the relation as:
........(1)
Differentiating equation (1) wrt t we get:
............(2)
When v = 2 ft/s
t₁ = 2.26 s
and t₂ = 0.73 s
Put the value of t₁ in equation (1) as :
x₁ = 14.23 ft
Put the value of t₂ in equation (1) as :
x₁ = 14.74 ft
For acceleration differentiate equation (2) wrt t as :
a = 12 t - 18.........(3)
Put t₁ and t₂ in equation 3 one by one as :
Hence, this is the required solution.
Answer:
Measurements most commonly use the International System of Units (SI) as a comparison framework. The system defines seven fundamental units: kilogram, metre, candela, second, ampere, kelvin, and mole.
