we did a lab and my observation chart is like this
when my mass is 1.4 kgs (height is 0.12m,distance is 1.0m,time is 0.87s,velocity is 1.1 m/s ,Eg is 1.6 and the Ek is 0.85)
when my mass is 2.14 kgs(height is 0.12m,distance is 1.0m,time is 0.88s,velocity is 1.1 m/s ,Eg is 2.8 and the Ek is 1.5)
Compare the speeds at the bottom of the ramp for the cart with 1.4 kgs and 2.4kgs masses.Find the percentage difference between the values.
To compare the speeds at the bottom of the ramp for the cart with different masses, you can use the velocity values provided in your observation chart.
For the cart with a mass of 1.4 kg, the velocity at the bottom of the ramp is given as 1.1 m/s.
For the cart with a mass of 2.14 kg, the velocity at the bottom of the ramp is also given as 1.1 m/s.
Since both velocities are the same, the percentage difference between the two values is 0%. This means that there is no difference in speed at the bottom of the ramp between the cart with a mass of 1.4 kg and the cart with a mass of 2.14 kg.
