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

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

A carmaker has designed a car that can reach a maximum acceleration of 12 meters/second2. The car’s mass is 1,515 kilograms. Ass
Vlada [557]
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
