horizontal and it was a typo

Edit 2: What does my teacher mean when he says he wants me to find the acceleration due to gravity? Does it mean find the centripetal acceleration?

Homework Statement I need to make a free body diagram of an object being twirled around on a string in a circular motion. What forces are acting on it and what are there equations? For example I know that the force of gravity is acting on the string so I am showing the Fg = mg equation on my...

Thanks so far i got u which is 32.75 I think but I don't know how to find the maximum height.

v = u + at? but how does that work I would get 0 = 0 + 0(6.55)

Homework Statement Find the initial velocity and the maximum height of the rocket. Angle = 90˚ Horizontal distance = 0 m Time = 6.55 seconds Homework Equations Suvat equations. The Attempt at a Solution s = ut + 1/2a(t^2) s = 6.55u 0/6.55 = u ? Please help!

Lol I don't know any of this...

It is the same as the u(h)?

Homework Statement Find the initial velocity and the maximum height θ = 28˚ horizontal range/distance/s = 68 m time = 6.30 s Homework Equations suvat equations not so sure which one though The Attempt at a Solution I think to find the initial velocity I use the equation...

Hi, I need someone to outline how to get the solution of the problem which is: An object 8.0 cm high is placed 80 cm in front of a converging lens of focal length 25 cm. Calculate the image position and height. Thanks, Eric
