Question 1

Solve the following  initial-value problem:   = 9.8 - 0.196v, v(0) = 48.
◦ v = 50 - e-0.196t
◦ v = 100 - 4e-0.196t
◦ v = 50 + 2e-0.196t
◦ v = 50 + e-0.196t
◦ v = 50 - 2e-0.196t

Question 2

A motorboat is travelling with a velocity of 40 ft/sec when its motor shuts off at time t = 0. Thereafter, its deceleration due to water resistance is given by   = -kv2,  where k is a positive constant. After 10 seconds, the boat's velocity is measured to be 20 ft/sec.
(a)  What is the value of k?
(b)  When will the boat slow to 5 ft/sec?
◦
(a)    (b)   100 s

◦
(a)   (b)  50 s

◦
(a)   (b)  70 s

◦
(a)   (b)  700 s
