How do you find the velocity after a collision

Physics
1 answer:
Evgen [1.6K]3 years ago
7 0

Answer:

In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

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 zero-order reaction has a constant rate of 2.30×10−4 M/s. If after 80.0 seconds the concentration has dropped to 1.50×10−2 M,
dolphi86 [110]

Answer:

Initial concentration of the reactant = 3.34 × 10^(-2)M

Explanation:

Rate of reaction = 2.30×10−4 M/s,

Time of reaction = 80s

Final concentration = 1.50×10−2 M

Initial concentration = Rate of reaction × Time of reaction + Final concentration

= 2.30×10−4 M/s × 80s + 1.50×10−2 M = 3.34 × 10^(-2)M

Initial concentration = 3.34 × 10^(-2)M
