Physics
A race car starts from rest on a circular track of radius 445 m. The car's speed increases at the constant rate of 0.380 m/s2. At the point where the magnitudes of the centripetal and tangential accelerations are equal, find the following. (a) the speed of the race car (b)...

A rotating wheel requires 8.00 s to rotate 29.0 revolutions. Its angular velocity at the end of the 8.00 s interval is 95.0 rad/s. What is the constant angular acceleration of the wheel? (Do not assume that the wheel starts at rest.)

Precalc/Triangles
Draw and solve any triangles satisfying alpha = 29 degrees a = 7 c = 14 I realize I need to draw a non-right triangle and label the sides but I am completely confused one what to do after I draw the triangle

Physics
A 7.45-g bullet is moving horizontally with a velocity of +348 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bulle...

Programming-Array
If i have a string with a word 'today' in it. If a user inputs a char (lets say b). how do I right the array to make it see if the char "b" is in the string today. LOOP??? int i; for(i=0; i<SIZE; i++) { guessedChar[i]; /*or*/ wordString[i]; }

Programming
int a = 10; int b = 5; int total = 0; printf("%d + %d = %d\n", a, b, total); printf("%d - %d = %d\n", a, b, total); printf("%d * %d = %d\n", a, b, total); printf("%d / %d = %d\n", a, b, total); /*Without an array*/ if(var == 1) { return ...

The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is heavier and rests on a ramp that is less steep. The boxes are released from rest at A and allowed to slide down the ramps. The two boxes have masse...

I'll help you but I'm not gonna right your code for you. What are you lost on?
