Explanation:
(a) Displacement of an object is the shortest path covered by it.
In this problem, a student is biking to school. She travels 0.7 km north, then realizes something has fallen out of her bag. She travels 0.3 km south to retrieve her item. She then travels 0.4 mi north to arrive at school.
0.4 miles = 0.64 km
displacement = 0.7-0.3+0.64 = 1.04 km
(b) Average velocity = total displacement/total time
t = 15 min = 0.25 hour
Hence, this is the required solution.
Answer:
Explanation:
given,
radius of circle = 1.8 m
mass of the ball = 0.1 Kg
linear speed of the ball = 27 m/s
angular velocity of orbit = ?
ω is the angular speed of the circle
the angular velocity of the orbit is
