Answer:
Explanation:
Impulse results in change of momentum
FΔt = mΔv
F = 0.030(50.0 - 0) / 0.010 = 150 N
The vertical portion of that force adds to his weight on the ice
Fmax = 60.00(9.81) + 150sin30 = 663.6 N
As this is above the ice strength, He takes a cold dip.
Inner planets are far warmer than outer planets. Due to distant of the sun
As the planets distant from the sun. The colder the get due to distance.
Answer:
Proof is given below
Explanation:
The length contraction is given by Δx = Δx' *√(1 - v² / c²)
where Δx' is the proper length and is measured in the frame where the object is at rest
Since the y' and z' axes are perpendicular to the direction of motion there is no contraction
So if you let V0 = Δy' * Δz' *Δx'
and V = Δy * Δz * Δx = Δy'* Δz' * Δx
Then
V = V0 * √(1 - v² / c²)
The angle between r (t = o) and r (t), is diresctly related to the direction pf the verlocity vector which is when t = 0, r(t = 0) = R(i^)θ = ωt
So, the speed of the mass at time (t0 is v(t) = ωR (v(t) in terms of ω and R)
the answer is v(t) = − Rωsin(ωt) + Rωcos(ωt)j^
