Need help with these physics problems?

[Trish M]

These two problems I have been working at for over a week and I can not figure them out. The first one is as follows.

A soccer ball is kicked with an initial speed of 12 m/s in a direction of 25 degrees abover th horizontal. Find the magnitude and direction of its velocity A) .250 s and B) .5 after being kicked C) is the ball at its greatest height before or after .5 s. Second one as follows

A trained sea lion slides from rest with constant acceleration down a 3 m long ramp into a pool pf water. IF the ramp is inclined at an angle of 23 degrees aove the horizontal and the coefficient of kinetic friction between the sea lion and the ramp is .26, how long does it take for the sea lion to make the splash into th pool.
Thank you so much for all help in advance
