Question

An airboat with mass 3.50 x 102 kg, including
passengers, has an engine that produces a net
horizontal force of 7.70 102 N, after accounting
for forces of resistance. (a) Find the acceleration of
the airboat. (b) Starting from rest, how long does
I take the airboat to reach a speed of 12.0 m/s?
2.
cAfter reaching this speed, the pilot tums off the
engine and. drifts to a stop over a distance of
50.0 m. Find the resistance force, assuming it's
constant.​

Answer 1

Answer:

An airboat with mass 3.50 3 102

kg, including the passen-ger, has an engine that produces a net horizontal force of 7.70 3 102

N,

after accounting for forces of resistance (see Fig. 4.7). (a) Find the accel-eration of the airboat. (b) Starting from rest, how long does it take the

airboat to reach a speed of 12.0 m/s? (c) After reaching that speed, thepilot turns off the engine and drifts to a stop over a distance of 50.0 m.Find the resistance force, assuming it’s constant.
