Homework Statement Iv'e been given a graphed parabola with each x interval at 0.1000s. From this I need to find R, Tt, H, V0, a and θ. Homework Equations Tt= 2 (Vsinθ/g) R= (V2sin2θ)/g H=(Vsinθ)2)/2g The Attempt at a Solution From observing the graph I know: dx and dy at every 1/10...

Thank you :approve:

For that I did Tt=2 (Vsinθ)/g Tt=2 (6.552sin35)/9.8 Tt= 0.7670s

Homework Statement A cannon shot a ball at 90° and reached 2.19m high. From this I need to find Vi of that and find time, Vx, Vy, Dx, and Dy of a projectile being shot from this cannon at 35.00°. I would just like to confirm I have done this correctly. Dy=2.19m θ=90.00° Homework Equations...

Ahhh, okay. Thank you for your help !

t=v/a 2d/a=t^2

The only equation I know that has velocity, acceleration and distance is : Δd=v1Δt + 1/2 aΔt^2

Distance and acceleration equations. We haven't learned anything with energy yet.

Force of friction ?

Homework Statement A 20.00kg curling stone is released at the hog line and moves 28.35m [W] to sit on the button and score a point. If the coefficient of kinetic friction between the stone and the ice is 0.0020000, what was the initial speed of the stone ? So we know: m=20.00kg...
