Beginning from rest, a block of mass m slides down a frictionless curve. after sliding downward by h = 0.60 m, the block encounters horizontal concrete and slides to a stop. the coefficient of kinetic friction between the block and the concrete is µk = 0.30. what is the stopping distance l?

b.

explanation:

10.0

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
