Finding angle and altitude using distance and time?

AI Thread Summary
To find angle and altitude using distance and time, kinematic equations are essential. The discussion emphasizes the need for clarity regarding the specific distance and time values provided. The relevant equations include d = v_0 sin(θ) t and 0 = (-g/2)t² + v_0 cos(θ)t, which can be used to solve for initial velocity (v_0) and angle (θ). Gravity is assumed to be 9.8 m/s² in these calculations. Understanding the context of the problem is crucial for applying the correct equations effectively.

Homework Statement


I need an equation for a physics project, and I'm not sure which to use. I am given the distance and time variables, however I don't have the angle or altitude they are looking for. Which equation do I need to use?

Homework Equations


Velocity related equations? fab five physics equations probably, I'm not sure.

The Attempt at a Solution


I'm thinking that I need to use gravity as 9.8, but don't know what the equation would be?? Thanks to those who help :P :P :P

That's not very clear! What "distance and time" do you mean? The distance and time at which the projective again returns to earth?
Then the equations you use are d= v_0sin(\theta) t and 0= (-g/2)t^2+ v_0 cos(\theta)t. That gives you two equations to solve for v_0 amd \theta.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
