A car is accelerating as it passes two checkpoints that are 35.17 meters apart. The car’s speed at the first checkpoint is 5.28 m/s. If the car's acceleration is 1.70 m/s^2, what is its speed at the second checkpoint?

Carbon 14 is a naturally occurring stable

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
