Answer:
v = 27 m/s
Explanation:
To find the speed of cars after the collision you take into account the momentum conservation law. Total momentum of both cars before the collision must be equal to the total momentum of both cars after the collision.
After the collision both cars traveled together, then you have:
(1)
m1: mass of the Toyota = 3-ton = 3000 kg
m2: mass of the taxi = 2-ton = 2000kg
v1: speed of the Toyota before the collision = 45m/s
v2: speed of the car before the collision = 0 m/s (it is at rest)
v: speed of both cars after the collision = ?
You solve the equation (1) for v:
Next, you replace the values of the rest of the variables:
hence, just after the collision both cars have a speed of 27m/s
Answer:
<h3>The answer is 2800 kg</h3>
Explanation:
The mass of the truck can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>2800 kg</h3>
Hope this helps you
this is first law of thermodynamics in which meaning of each term is given as
= change in internal energy
Q = Heat given to the system
W = work done by the system
so here we will have
∆U=Q-W , which means <u>Change in internal energy</u> in a system is equal to <u>heat given</u> added, minus <u>work</u> done by the system. the units for these variables are in <u>joule</u> .
Answer:
