Jim(mass=100kg) rollerblades on a smooth horizontal floor at a constant speed of 2.0 m/s for a distance of 5m in 5 seconds. what is the power in this process? (assume g is 10 m/s^2)

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Me with this and you will be marked brainliest

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
