The position vector for an electron is R = (5.0 m)i – (3.0 m)j + (2.0 m)k.
(a) Find the magnitude of 7.
(b) Sketch the vector on a right-handed coordinate system.
A moderate wind accelerates a pebble over a horizontal xy plane with
a constant acceleration a =(5.00 m/s2) i + (7.00 m/s2) j . At time t=0, the velocity is 4.00 (m/s) i. What is magnitude of its velocity when it has been displaced by 12.0 m parallel to x-axis? Give three significant figures.
