Answer:

The  maximum  velocity is  a_{max} =  1.96 m/s^2

Explanation:

From the question we are told that

      The coefficient of static friction is  \mu  =  0.20

     

Generally the maximum acceleration can be mathematically represented as

          a_{max} =  \mu  *  g

Where g is  the acceleration due to gravity and the value is  g  = 9.8 \ m/s^2

substituting vlues

        a_{max} =  0.20  *9.80

       a_{max} =  1.96 m/s^2

Find the instantaneous acceleration at t=ls for an object moving along a straight axis with velocity function:
Maru [420]
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

What is the force when an object exerts 15 pascal pressure on a square surface of side 5 meters
olga55 [171]

Answer:375N

Explanation:

pressure =15 pascal

Length of side =5 m

Area=length x length

Area=5 x 5

Area=25 m^2

Force=pressure x area

Force=15 x 25

Force=375N

A bicycle has wheels of 0.8 m diameter. The bicyclist accelerates from rest with constant acceleration to 22 km/h in 11.6 s. Wha
larisa [96]

Answer:

α = 1.32 rad/s²

Explanation:

given,

diameter of the bicycle = 0.8 m

radius of the bicycle = 0.4 m

initial speed of the bicyclist,u = 0 m/s

final speed of the bicyclist,v = 22 Km/h = 22 x 0.278

                                           = 6.12 m/s

time,t = 11.6 s

acceleration =\dfrac{v-u}{t}

                     =\dfrac{6.12-0}{11.6}

                    =0.53 m/s²

we know,

    a = α r

\alpha=\dfrac{a}{r}

\alpha=\dfrac{0.53}{0.4}

  α = 1.32 rad/s²

the angular acceleration of the wheels is equal to α = 1.32 rad/s²
