Im having trouble finding the y velocity. I am not sure where to start.

Thanks for your response.If air resistance is not considered, how do I find out the vertical and horizontal velocities at the end of the ramp? For the equations, I would think just the usual kinematic equations, separated into horizontal and vertical components.

1. A skateboarder starts at the bottom of a 1 metre ramp, with an incline of 30 degrees. The skateboarders initial velocity is 7m/s. How far will the skateboarder land from the end of the ramp? I firstly worked out the hypotenuse and adjacent lengths of the ramp. I then worked out the...

Hi tinytim, the ruler is being rotated about 45 degrees and then released. It oscillates back and forth. thanks

Hi everyone, Could someone please help me with the fundamentals of oscillatory motion. A 1 metre ruler is suspended on both ends by two strings attatched to retort stands. The length of the string is increased to observe the increase in period of oscillation. I need to know the...
