A car of mass 1420 kg is on an icy driveway inclined at an angle of 26◦
.The acceleration of gravity is 9.8 m/s2
If the incline is frictionless, what is the
acceleration of the car?
Answer in units of m/s2

How to tell if a molecule is polar or nonpolar with electronegativity

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

Aspacecraft that renters the earth’s atmosphere drastically slows down. the amount of kinetic energy the spacecraft has as it reenters the earths atmosphere
