Solve for v.

s = vt + 16t^2
Option 1: v = s – 16t

Option 2:v=s/t -16t^2;t=o

Option 3: v = s/t – 16t; t cannot = 0

Option 4: t/s-16t^2;s-16t^2=0

An isolated 3 kg object initially at rest explodes into 3 fragments. One fragment hass a mass of .50 kg and flies off along the negative x axis at a speed of 2.8 meters per second, and another has a mass of 1.3 kg and flies off along the negative y axis at a speed of 1.5 m/s. What is the speed and direction of the third fragment?

Solve the equation without using logarithms.

1. 4^5x = 16^2x-1


Solve the equation, First express your answer in terms of natural logarithms (For instance, x=(2+ 1n 5) / (1n 3)). Then use a calculator to find an approximation for the answer.

2. 2^x = 3^x-1


3. e^2x = 5

Please show all work and formula used to get this answer.

I Thank You All in advance.

I have a conflict between math and physics.
T1 and T2 are strings that go from the ceiling and hold 8 kg.
(Gravity = 10 m/s in this calculations so 8kg=80Newton)
http://img149.imageshack.us/my.php?image...
angle A=60
angle B=53
I used the Law of sines:
so:
t2/sin53 = t1/sin 60
t1=t2*sin60/sin53=1.0842t2
t1=1.0842*t2
--------------------------------------...
but if I take the vectors and find how much each is pulling to the X axis and to the Y axis get that:
t1=t2*cos60/cos53=0.8...
Whats wrong?
