1. A Level Physics - finding resultant velocity at bottom of a frictionless incline, with no angle provided?
2. Hi, I am currently working through a problem set and I'm being asked to find the speed of a cart (roller-coaster) after it has traveled down a slope (from points A to B). The trouble is, I've not been given any angles other than the right angle, and no information regarding distance travelled.
The only information I have is the mass of the cart (Mc), the hight from which it is released from rest (hA), and I have been asked to assume acceleration due to gravity as 10ms-1.
Mc=6000N
hA=50m
g=10ms-13. Am I being a bit dim here? The way I see it, without the angle of inclination I won't be able to find the resultant velocity right? Regardless of the inclination being frictionless, there would still be a reaction force that would effect the velocity, but without the angle I can't resolve that either? I'm a bit stumped by this.
Any assistance anyone could lend regarding this would be very much appreciated.
