Hi! Just been doing some physics practice problems trying to get ready for my test next week and I cant seem to get the right answers. Please show your work and the final answer! Thank you soo much I really appreciate it!

1. A girl on the edge of a vertical cliff 17.7 m high throws a stone horizontally away from the cliff with a speed of 25.3 m/s. How far from the base of the cliff does it land?

2. Two forces are applied to a 9.6 kg object: F1 = 4.9 Nj and F2 = 9.8 Nk. What is the magnitude of the resulting acceleration of this object?
