According to the position vs time graph, the <em>average</em> <em>velocity</em> of the motorcycle is the change in position divided by the change in time. Also, note that the slope is linear and positive throughout the 5 hours, it doesn't change direction.
Therefore, we have
Avg velocity = change in direction/change in time
Avg velocity = (150km - 30km)/(5h - 0h)
Avg velocity = 24km/hr south.
Answer:
mass is lifted 1.8 m. What is the potential energy of the mass 4. A 100 kg
Answer:
<h2>2 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula

v is the velocity
t is the time taken
From the question we have

We have the final answer as
<h3>2 m/s²</h3>
Hope this helps you
