Starting from home, you bicycle 25 km north in 2.4 h and then turn around and pedal straight home in 1.4 h . What are your (a) d
AnnZ [28]

Answer:

Part a)

d = 25 km

Part b)

v_{avg} = 10.42 km/h

Part c)

v_{avg} = 17.86 km/h

Part d)

Displacement for entire trip = 0

Part e)

Average velocity for entire trip will be zero

Explanation:

Part a)

Displacement after t = 2.4 hours is the straight line distance between initial and final positions

so we have

d = 25 km

Part b)

Average velocity is defined as

v_{avg} = \frac{displacement}{time}

v_{avg} = \frac{25 km}{2.4 h}

v_{avg} = 10.42 km/h

Part c)

During his return journey the displacement will be same

displacement = 25 km

time = 1.4 h

so average velocity is defined as

v_{avg} = \frac{25 km}{1.4 h}

v_{avg} = 17.86 km/h

Part d)

Displacement for entire trip = 0

as initial and final position will be same

Part e)

Average velocity for entire trip will be zero
