a car having an initial velocity of 6 m/s east slows uniformly to 2 m/s east in 2.0 s what is the acceleration of the car during the 4.0 seconds interval?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Aparticle moves in a circle 1.50 m in radius . through what angle in radians does it rotate if it moves through an arc length of 2.50m? what is the angle in degrees?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
