Answer:
speed of masses after collision = 2m/s
Explanation:
Using the formula for inelastic collision;
m1u1 + m2u2 = (m1+m2)v
Where m1 is mass of body 1
m2 is mass of body 2
u1 is initial velocity of body 1
u2 is initial velocity of body 2
v is final velocity
m1 =2kg , u1=5m/s , m2=3kg, u2=0(body at rest) v=?
(2*5) + (3*0)= (2+3)v
10=5v
v = 10/5
v=2m/s
Answer:
a. ≈ 1.22449s
b. ≈ 14.69387m
c. ≈ 0.532415s
Explanation:
Because we are trying to find when it is at it's highest point we can safely say that it's velocity at that point is 0m/s,
therefore we can use the equation:
and do some algebra to get:
Now we plug in our values (note that this is assumed to be on Earth and that because it says that upwards is positive, we set g to be negative to say that it is pointing down):
To find the final height we can use:
and plug in our values to get:
To find the time we can use the time dependent position equation:
This here can be made into a quadratic equation like so (xi is set up to be 0m, so the equation wont have it):
Here we can use the quadratic formula:
And now it would be best if we put in our values (xf = 5m because that is our question):
Finally we have simplified enough to be worth solving for:
We get:
and
Because time is always positive we want to choose the plus answer.
We all know the temperature gets higher as particles bounce off each other, but to slow it they have to be more spread out and moving in a slower motion which the enzymes help this process.
