1. ### For positive constants k and g, the velocity,v , of a particle of mass m at time t is given by?

a = dv/dt = mg/k*(-k/m)*e^(kt/m) = -g*e^(kt/m) at t = 0 the rate of change a = -g = -9.8m/s^2 at t = 2 then a = -g*e^(2k/m) This means that the velocity is reducing since the value of a is negative

10. ### What should be the spring constant k of a spring designed to bring a horizontally moving car of mass 967 kg to rest from a speed of 22.7 m/s?

1/2 k Δx ^2 = 1/2 m v^2 k Δx < = m a then 1/2 k (m a / k)^2 >= 1/2 m v^2 m a^2 / k >= v^2 k <= m (a / v)^2 k <= 967 (5.6*9.8 / 22.7)^2 = 5652 N/m
