Find the instantaneous acceleration at t=ls for an object moving along a straight axis with velocity function:
v(t)= -t3+5t

Answer:

A. 2m/s^2

B. 5m/s^2

Answers

The answer is A.
Explanation:
We know that the average acceleration a for an interval of time Δt is expressed as:

a = Δv
Δt
where Δv is the change in velocity that occurs during Δt.
e formula for the instantaneous acceleration a is almost the same, except that we need to indicate that we're interested in knowing what the ratio of Δv to Δt approaches as Δt approaches zero.

We can indicate that by using the limit notation.

So, the formula for the instantaneous acceleration is:

a = lim Δv
Δt→0 Δt

B. Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.

Answers

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

From the question we are told

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the

shuttlecock when it hits the ground? Show your work below.

Generally the equation for acceleration is mathematically given as

[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]

Where

acceleration is still -9.81 m/s2,

Hence,

[tex]V^2-U^2=2(-9.81)*-H[/tex]

Therefore

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

A force of 36 N pushes a box that is 12.2 kg. The box is sliding horizontally 2.6 m/s to the left. What is the coefficient of friction? (Could you draw a Force Diagram?)

Answers

The coefficient of friction on the box sliding to the left is 0.3.

The given parameters;

applied force , F = 36 Nmass of the box, m = 12.2 kgvelocity of the box, v = 2.6 m/s

The acceleration of the box is calculated as follows;

[tex]F = ma\\\\a = \frac{36}{12.2} \\\\a = 2.95 \ m/s^2[/tex]

The coefficient of friction on the box is calculated as follows;

[tex]\mu_k = \frac{a}{g} \\\\\mu_k = \frac{2.95}{9.8} \\\\\mu_k = 0.3[/tex]

Thus, the coefficient of friction on the box is 0.3.

a box has a length of .5 m and a width of .1m. if the box exerts a force of 10 N on the floor, what is the pressure of the box on the floor

Answers

Answer:

The pressure of the box on the floor is 200 Pa

Explanation:

Given,

Length of the box=0.5m

Width of the box= 0.1m

∴Area of the box, A= (0.5 X 0.1) sq.m

= 0.05 sq.m

We know,

Pressure, P= F/A

= 10/0.05 Pa

= 200 Pa

∴The pressure of the box on the floor is 200 Pa
