# Abicycle wheel has radius r = 32.0 cm and mass m = 1.82 kgwhich you may assume to be concentrated on the outside radius. a resistive force f = 100 n (due to friction with theground) is applied to the rim of the tire. a force f is applied tothe sprocket at radius r by the bicycle chain such that the wheelhas an angular acceleration of alpha(a) = 4.50 rad/s2. the tire does notslip with the ground, and the lower part of the chain (not shown)exerts no force. what is the combined mass of the bicycle and rider? hint: the force f also acts onthe front sprocket of the bicycle.   ### Another question on Physics Physics, 22.06.2019 06:00

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.) Physics, 22.06.2019 19:50
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.)
