what is the acceleration produced by the resultant force acting on an object if the coefficient of friction acting between the b
LenKa [72]

The acceleration of the block is -0.98 m/s^2

Explanation:

The expression for the force of friction acting on the block is (assuming the surface is horizontal and flat):

F_f = -\mu mg

where

\mu is the coefficient of friction

m is the mass of the block

g is the acceleration of gravity

and where the negative sign means the direction of the force is opposite to that of the motion of the block

If this is the only force acting on the object, then this is also the resultant force, so we can rewrite Newton's second law as:

F=ma\\-\mu mg = ma

where

a is the acceleration of the block

Re-arranging the equation,

a=-\mu g

And so this is the expression for the acceleration of the block acted upon the force of friction.

In this problem, we have:

\mu=0.1

g=9.8 m/s^2

Solving,

a=-(0.1)(9.8)=-0.98 m/s^2

Which of the following statements is true about the scientific process? The hypothesis is always supported in the end / You can
Pachacha [2.7K]
The correct answer is the statement #3. The statement that says: your hypothesis must be testable, is a true statement about the scientific process. IT will be truly unreasonable and a waste to be doing experiments on a hypothesis that is not even possible to solve.

A projectile is fired at an upward angle of 35.6° from the top of a 208-m-high cliff with a speed of 170-m/s. What will be its s
sdas [7]

Answer:

Final velocity is 181.61 m/s at angle 40.44° below horizontal.

Explanation:

Initial horizontal velocity = 170 cos 35.6 = 138.23 m/s

Final horizontal velocity = 138.23 m/s

Considering vertical motion of projectile:

Initial vertical velocity, u = 170 sin 35.6 = 98.96 m/s

Acceleration, a = -9.81 m/s²

Displacement, s = -208 m

We have v² = u² + 2as

Substituting

             v² = 98.96² + 2 x -9.81 x -208

             v = 117.79 m/s

Final velocity,

            v=\sqrt{138.23^2+117.79^2}=181.61m/s

            \theta =tan^{-1}\left ( \frac{117.79}{138.23}\right )=40.44^0

Final velocity is 181.61 m/s at angle 40.44° below horizontal.

If an object accelerates at 40 m/s^2 in four minutes ("careful this is in minutes),
yaroslaw [1]

Change in speed = (acceleration) x (time)

4 minutes = 240 seconds

Change in speed = (40 m/s²) x (240 seconds)

Change in speed = <em>9,600 m/s</em>

What you're actually describing here is a car pulling 4 G's for 4 minutes, and ending up going 21,475 miles per hour.

The driver would definitely NOT get a speeding ticket, because nobody could catch him.

Also, his car would heat up and shoot flames from atmospheric friction.

(He could avoid this with some fancy steering, leave the atmosphere, and end up in low-Earth-orbit.)

Actually, I hope there's nobody in the car.  His experience wouldn't be pretty.
