How Fast Can Jim and Rob Reach the Top of the Slope?
What is the acceleration of Rob?
The acceleration of Rob during the upward motion is calculated based on the given data. How can we determine Rob's acceleration?
Acceleration of Rob:
The acceleration of Rob can be found using the kinematic equation:
v = u + at
where:
- v is the constant velocity of Rob
- u is the initial velocity = 0
- a is the acceleration of Rob
- t is the time of motion of Rob = 5 minutes = 300 seconds
By substituting the values into the equation, we can calculate the acceleration of Rob.
The acceleration of Rob, denoted as 'a', can be calculated as follows:
v = u + at
0 = 0 + a(300)
a = 0 / 300
a = 0 m/s²
Therefore, the acceleration of Rob is 0 m/s². This implies that Rob is moving at a constant velocity during the upward motion.
