Starting from rest, a 5.40-kg block slides 2.60 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is u, = 0.436. (a).Determine.the work done by the force of gravity. Enter a number. is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J (b) Determine the work done by the friction force between block and incline. The response you submitted has the wrong sign. J (c) Determine the work done by the normal force. (d) Qualitatively, how would the answers change if a shorter ramp at a steeper angle were used to span the same vertical height? This answer has not been graded yet.
