How long would it take a 3.4 kg bike with 79 kg rider traveling at 18.6 m/s to stop if 867 n of force is applied to the brakes?
Answers: 1
is the total mass of the bike and the rider
is the initial velocity
is the force applied to the brakes
with the following equation:
(1)
(2)
(3)
(4) This is the magnitude of the acceleration, however, since the final velocity is 0 m/s, this means the direction is negative
(5)
:
(6)
is the final velocity (the bike stops)
(7)
(8)
This iste time it takes to the bike to stopAnother question on Physics

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
