Homework Statement
Car P is 1km from finish line with a speed of 35ms-1 and a uniform acceleration of 2/5ms-2
Car Y is 1.2km from finish line going at 44ms-1 and a uniform accelr of 1/2ms-1
show that Y passes p 220m before the finish line.
Homework Equations
v2=u2+2as
s=vt-1/2at^2...
well i got s=vt-1/2at^2 for C is well s=d and t=T+2 (?) thus it would be d=v(T+2) - .5(a)(T+2)^2 and for D it would be d=6(T)-.5(a)(T)^2.
so it would be 6(T)-.5(a)(T)^2=v(T+2) - .5(a)(T+2)^2 thus i ended up with 6T-vT-2v
+2aT+2a that's it, I'm lost and I'm sure that its wrong
Homework Statement
a stone is thrown vertically upwards with a speed of u metres per second. a second stone is thrown vertically uppwards from the same point with the same initial speed but T seconds later than the first. prove that they collide at a distance (4u^2-g^2T^2)/(8g) metres above...
I'm LOST! Car is suppose to overtake truck but at what velocity?
two cars C and D move in the same direction in parrallel lanes of a straight road. C starts from rest and begins to move with a constant acceleration. at that instat the C begins to move it is overtaken by D, which is moving with...
