Answer:

200m

Explanation:

Velocity = displacement/time

V = s/t

Given

Velocity = 40m/s

Time = 5 secs

Therefore

40 = S/5

Cross multiply

S = 40 x 5

S = 200m

The vehicle travelled 200m before stopping

Answer: 100 m

Explanation:

Initial speed(u) = 40 m/s

Final speed(v) = 0 m/s

Acceleration = v-u/t

=> 0-40/5

=> 8 m/s^2

Displacement= s

=> 2as = v^2-u^2

=> 2(-8)(s) = 0 - (40)^2

=> -16s = -1600

s = 100 m

We can say the vehicle move 100 meters before stopping.

If an electric current of 8.50 A flows for 3.75 hours through an electrolytic cell containing copper-sulfate (CuSO4) solution, t
muminat

Answer:

75.5g

Explanation:

From the ionic equation, we can write

CU^{2+}+SO^{2-}_{4}\\

next we find the number of charge

Note Q=it

for i=8.5A, t=3.75 to secs 3.75*60*60=13500secs

hence

Q=8.5*13500\\Q=114750C

Since one faraday represent one mole of electron which equal 96500C

Hence the number of mole produced by 114750C is

114750/96500=1.2mol

The mass of copper produced is

mol=\frac{mass}{molar mass} \\mass=mole*molar mass\\mass=1.2*63.5\\mass=75.5g

Hence the amount of copper produced is 75.5g
