During a one-hour trip, a small boat travels 80.0 km north and then travels 60.0 km east. The average velocity of the boat was 100 km/h.

True or false

If a body is moving in uniform motion, then there are no external forces acting on the body.

True or false

Answer #1

a)

magnitude of distance is

speed of boat is

Ans ====> true

b)

the body moving in uniform motion, so velocity remains constant therefore aceleration is zero, then there are no external forces acting on the body.

Ans ====> true

c)

The force due to air resistance always opposes the direction of motion.

Ans =====> true
