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...

i got that T=(2gt+1)/t

such as the time it takes for them to collide? and their initial velocity perhaps?

oh yeah well its going upwards so yeah. well that the y's are the same. that's all i am able to assume

what do you mean with coordinate axis?

well i got u(X-T)+ .5(g)(X-T)^2= uT + .5(g)T^2 thus it is equal to uX-2uT+.5gx^2-.5gXT that's all i could get

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...
