A box slides down a ramp inclined at 24◦ to the horizontal with an acceleration of 1.7 m/s 2 . The acceleration of gravity is 9.

dsp73

Answer:

Explanation:

In friction, the coefficient of friction formula is expressed as;

$\mu = \frac{F_f}{R}$

Ff is the frictional force = Wsinθ

R is the reaction = Wcosθ

Substitute inti the equation;

$\mu = \frac{Wsin \theta}{W cos\theta} \\\mu = \frac{sin \theta}{cos\theta} \\\mu = tan \theta$

Given

θ = 24°

$\mu = tan 24^0\\\mu = 0.445\\$

Hence the coefficient of kinetic friction between the box and the ramp is 0.445

If the flea jumps straight up, how high will it go? (Ignore air resistance for this problem; in reality, air resistance plays a

Savatey [412]

Answer:

The flea will reach to a height of 5.2 cm.

Explanation:

Let us assume it is given that, a flea reaches a takeoff speed of 1.0 m/s over a distance of 0.50 mm.

Initial speed, u = 1 m/s

Initial distance, x = 0.5 mm

We need to find the height reached by the flea. Using third equation of motion to find it.

At maximum height, its final speed, v = 0

$v^2-u^2=2ah$

Here, a = -g

$-u^2=-2g(h-x)\\\\1^2=2\times 9.8\times (h-0.5\times 10^{-3})\\\\h=0.052\ m$

h = 5.2 cm

So, the flea will reach to a height of 5.2 cm.

gregori [183]

Because solar panels are man made so they can shut down, not move, break, etc...? Don’t judge me, it’s just a guess.
