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 0.5-kilogram ball is thrown vertically upward with an initial kinetic energy of 25 joules. Ap-proximately how high will the ba
tatuchka [14]
It's gravitational potential energy at the top will roughly equal it's kinetic energy when it was released (a little is lost to air resistance).  Note this will assume the release point is zero potential energy.  (we are free to define it that way, just letting you know).  Gravitational potential energy is mgh.
mgh=25J
h=25J/(0.5kg x 9.81m/s^2) = 5.097m
So it goes about 5.1 meters above the point where it was released
