Answer:
The time taken is
Explanation:
From the question we are told that
The speed is
The length of the tennis court
Generally the time taken is mathematically represented as
=>
Answer:
11 m/s
Explanation:
Impulse equals change in momentum.
I = Δ(mv)
Since mass isn't changing:
I = m Δv
16 Ns = (2.0 kg) (v - 3.0 m/s)
v = 11 m/s
The coefficient of linear expansion is
<em>(change of length, feet) / (original length, feet)</em> per °F.
Since the numerator and denominator of the fraction have the same
unit, the coefficient turns out to be just a number, with no unit.
Answer:
The diagonal of the parallelogram PBCA is the resultant force R, which forms two scalene triangles with the forces F1 and F2. Since the sum of all the angles within a triangle is 180°, we can write γ function of α and β. The resultant force can also be calculated analytical, using force projections.
