The first part is pretty straight forward, vₓ=v₀+a(t). Convert final velocity to m/s to get 97.2m/s. v₀=0, a=4. Solving for t yields 24.3 seconds.
For the second part use "vₓ^2(final velocity) = v₀^2(initial velocity) + 2a(Δx). Final velocity is 97.2m/s, initial velocity is 0, acceleration is 4m/s^2. Solving for Δx yields 1181.53 meters.

Answer:
Explanation: This is a type of radioactive decay and all the radioactive process follow first order kinetics.
Half life is the time required to decompose half of the reactants. thus after every half life the reactant will decompose to half of its present value.
Now, to calculate the number of half lives, we use the formula:
where,
a = amount of reactant left after n-half lives = ?
=Let Initial amount of the reactant = 100 g
n = number of half lives
Answer:
0.000136kg/m3
Explanation:
13.6 / 1000 = 0.0136kg/cm3
0.0136 / 100 = 0.000136kg/m3
