A driver is on a highway that has provided an odometer test zone in which signs mark
every
kilometre for 25 km. He checks his
watch and sees that it is 1:16 P. M. when he
passes the 5.0 km marker. When he passes
the 25 km marker, his watch reads 1:31 P. M.
What was his speed for that section of the
test zone?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
