Oduvanchick [21]

Answer:

The the speed of the car is 26.91 m/s.

Explanation:

Given that,

distance d = 88 m

Kinetic friction = 0.42

We need to calculate the the speed of the car

Using the work-energy principle

work done = change in kinetic energy

$W=\Delta K.E$

$\mu\ mg\times d=\dfrac{1}{2}mv^2$

$v^2=2\mu g d$

Put the value into the formula

$v=\sqrt{2\times0.42\times9.8\times88}$

$v=26.91\ m/s$

Hence, The the speed of the car is 26.91 m/s.

What is the name given to the initial 150 counts in 2 minutes?

Whitepunk [10]

Divide CFU of Dilution. Divide the CFU of the dilution (the number of colonies you counted) by the result from step 4. For this example, you work out 46 ÷ 1/1000, which is the same as 46 x 1,000. The result is 46,000 CFU in the original sample.

A boat, whose speed in still water is 2.50 m/s, must cross a 285-m wide river and arrive at a point 118m upstream from where it

son4ous [18]

The figure shows the arrangement of system

The velocity of boat can be resolved in to two

Horizontal component = vcos θ = 2.50 cos 45 = 1.768 m/s

Vertical component = vsin θ = 2.50 sin 45 = 1.768 m/s

Due to horizontal component the boat arrive arrives upstream,

Total horizontal velocity = 1.768 - Vr, where Vr is the velocity of river.

Total time taken to cross the river = width of river/ Vertical component of velocity

t = 285/1.768 = 161.20 seconds

So 118 meter is traveled at a velocity of 1.768-Vr in 161.20 seconds

That is 118 = (1.768-Vr)*161.20

1.768 - Vr =0.732

Vr = 1.036 m/s

So velocity of river flow =1.036 m/s
