1.) A stone is thrown with an initial velocity of 7.0m/s. the acceleration of the stone is constant and has the value of -9.8m/s to the power of ((2)). What is the velocity of the stone after .50 s?(adsbygoogle = window.adsbygoogle || []).push({});

I put 2.1 not sure if it's right.

2.) An airplane starts from rest and accelerates at 10.8 m/s to power of ((2)). What is its speed at the end of a 400m long runway.

I don't really know where to begin.

3.) A displacement vector is 34.0m in length and is directed 60.0 degrees east of north. What are the components of this vector?

Again I don't even know where to begin.

It would be nice if someone could explain these to me. Thanks in advance.
