Does mass affect the final velocity of an object if the object begins with a high initial velocity? Why or why not?

1 answer:

5 0

The speed of a falling object is not affected by the mass of the object ... This means that if both accelerate at the same rate, then the force acting on objects of different ... time and initial velocity andnot dependent on the mass of the object at all

Distanţa Buzău - Iaşi este de 72 km . Aflaţi timpul în care un autovehicul parcurge această distanţă, dacă are viteza de 72 km p

GrogVix [38]

The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you

Answer:

3600seconds

Explanation:

Given parameters:

Distance = 72km

Speed = 72km/hr

Unknown:

Time it takes for the vehicle to travel the distance = ?

Solution:

Speed is the distance divided by time;

Speed = $\frac{distance}{time}$

time = $\frac{distance}{speed }$

Insert the parameters;

time = $\frac{72}{72}$ = 1hr

The SI unit of time is in seconds;

3600 seconds is 1hr

The time is 3600seconds

A wind is blowing a small ice fishing shed along the ice to the east with a 800N force. The shed weighs 2,200N. What would the l

e-lub [12.9K]

Answer:

0.36

Explanation:

The maximum force of friction exerted by the surface is given by:

$F_f = \mu N$ (1)

where

$\mu$ is the coefficient of friction

N is the normal reaction

The shed's weight is 2200 N. Since there is no motion along the vertical direction, the normal reaction is equal and opposite to the weight, so

N = 2200 N

The horizontal force that is pushing the shed is

F = 800 N

In order for it to keep moving, the force of friction (which acts horizontally in the opposite direction) must be not greater than this value. So the maximum force of friction must be

$F_f = 800 N$

And substituting the values into eq.(1), we can find the maximum value of the coefficient of friction:

$\mu = \frac{F_f}{N}=\frac{800}{2200}=0.36$
