A roller coaster car is near the bonom of its tracks
shown in Figure 3. At this point, the normal force
on the roller coaster is 3.5 times its weight. The speed
of the roller coaster is 26 m/s. Determine the radius of the tracks curvature

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
