Answer:

Force, F = 57.134 N  

Explanation:

It is given that,

Mass of the sled, m = 53 kg

Coefficient of kinetic friction, \mu_k=0.11

We need to find the force of friction felt by sled. The force of friction is given by :

F=\mu mg

F=0.11\times 53\ kg\times 9.8\ m/s^2

F = 57.134 N

So, the force of friction felt by the sled is 57.134 N. Hence, this is the required solution.

What is the momentum of a ten ton truck which is sitting still?
ANTONII [103]

The momentum of the truck is given by:

p = mv

p = momentum, m = mass, v = velocity

There isn't too much work to do here; the truck is at rest, therefore its velocity is 0. This means the product of m and v is 0, giving the momentum as 0.

What is the function (job) of the genes in protein synthesis (how proteins are made in the cell)?
Alborosie

Answer:Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.

Select the correct answer. A ball is thrown straight down from the top of a building at a velocity of 16 ft/s. The building is 4
BartSMP [9]

Answer:

The ball takes 5s to reach the ground

Explanation:

in order to solve this problem we use the kinematics equation with gravity as acceleration:

h=v_0t+1/2*gt^2

we replace the values

0=1/2*32t^2+16t-480

We solve this quadratic equation:

t=5s

t=-6s   (this solution has not physical sense)

A rolling ball with a mass of 1.01 kg crashes into a wall. The wall exerts a force of 2.40 Newtons and stops the ball. What was
klemol [59]

Answer:

Acceleration, a = 2.38m/s²

Explanation:

Given the following data;

Mass = 1.01 kg

Force = 2.4N

To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

  • F represents force.
  • m represents the mass of an object.
  • a represents acceleration.

Making acceleration (a) the subject, we have;

Acceleration, a = \frac{F}{m}

Substituting into the equation, we have;

Acceleration, a = \frac{2.4}{1.01}

<em>Acceleration, a = 2.38m/s²</em>

<em>Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square. </em>
