Question

A ship weighing 30,000 metric tons (1 metric ton = 1,000 kg) starts from rest.
Assuming that the resistance in kg to motion is 1500v, where v is the speed in
m/sec and the thrust on the ship by the propellers is 15,000 kg, what was the
speed of the ship 10 minutes after it has departed?
4.72 m/s
2.55 m/s
0.049 m/s
5.95 m/s

A parachuter of mass 139 kg above Earth (g = 10 m/s2) experiences a drag force modeled by -0.04 v (N). If the parachuter is released from rest, how fast, in m/s, will the jumper be falling after 1,027 s? (Assume the parachuter doesn't reach the ground in this amount of time.)(I want the speed.) (Please answer to the fourth decimal place - i.e 14.3225)

A flea jumps by exerting a force of 1.19 ✕ 10−5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.700 ✕ 10−6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.40 ✕ 10−7 kg. Do not neglect the gravitational force. (Assume that the breeze blows in the +x-direction and that the +y-direction is up.) Magnitude= ? Direction (counterclockwise from x axis)= ?
