A block of mass 2 kg slides down ramp 1 with a height of 3 m. It then slides for 1 m on a surface with a kinetic coefficient of
friction of 0.4. Next the block slides up a frictionless ramp 2. What is the potential Energy of the block at the top of Ramp 1
1 answer:
Answer:
PE = 58.8,J
Explanation:
The potential energy at the top of ramp1 can be found by the application of the formula PE = mgh
Where PE =potential energy
m = mass of block = 2kg
g = acceleration due to gravity = 9.80m/s²
h = height of the top of the ramp from its bottom where the block is initially positioned = 3m
PE = 2×9.8×3 = 58.8J

False, he is a catcher, and he is in new york
Answer:
∆L=aL∆T
Explanation:
that's the answer for your Question
1) 15 / 12 = 1.25 ratio
2) to increase acceleration 1.25 times (with same F, or same engine) you have to lower mass 1.25 times
3) 1515/1.25 = 1212 kg
choose A
No, there isn't. Please consult your doctor if this is the case with yours or someone you know.
