Question

A girl is riding a bicycle at a constant velocity of 3.0 m s−1 along a straight road. At time t = 0, she passes

a boy sitting on a stationary bicycle. At time t = 0, the boy sets o" to catch up with the girl. His velocity

increases from time t = 0 until t = 5.0 s, when he has covered a distance of 10 m. He then continues at a

constant velocity of 4.0 m s−1.

a Draw the displacement–time graph for the girl from t = 0 to 12 s.

b On the same graph axes, draw the displacement–time graph for the boy.

c Using your graph, determine the value of t when the boy catches up with the girl.

Answer 1

Answer:

Draw the displacement–time graph for the girl from t = 0 to 12 s.

Explanation:

Draw the displacement–time graph for the girl from t = 0 to 12 s.

Answer 2

Explanation:

Given things are

A girl is riding a bicycle at a constant velocity of 3.0 m s−1 along a straight road. At time t = 0, she passes a boy sitting on a stationary bicycle. At time t = 0, the boy sets o" to catch up with the girl. His velocity increases from time t = 0 until t = 5.0 s when he has covered a distance of 10 m. He then continues at a constant velocity of 4.0 m s−1.

The time is 10 s
