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?
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.
