A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. All frictional forces are considered to be negligible. A wooden block of mass 3m lies on the bottom of a frictionless circular track with a radius R. A small bullet of mass m is fired from a gun with an initial velocity v 0. block sliding back down the ramp. Access to over 100 million course-specific study resources, 24/7 help from Expert Tutors on 140+ subjects, Full access to over 1 million Textbook Solutions. id=1XCYoAEACAAJ '' > Physics: a first Course which there is between. The coefficients of friction for the block on the ramp are: s = 0.6 and k = 0.5.. Write a program that reads students names followed by their test scores. A 200 -g block is pressed against a spring of force constant 1.40 $\mathrm{kN} / \mathrm{m}$ until the block compresses the spring $10.0 \mathrm{cm} .$ The spring rests at the bottom of a ramp inclined For example, if use of the equation expressing a particular concept is worth 1 point, and a students solution embeds the application of that equation to the problem in other work, the point is still awarded.
