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.
