After a snow storm, Juliet steps out onto narrow balcony and, from a point 7.0 m above the ground, throws
a snowball at Romeo at an angle of
20° above
the horizontal, Down below, Romeo catches the
ball 1.3 seconds later when It is 1.0 m
above
the ground
a) what was the magnitude of the snowball's initial
Velocity?
b) At what distance horizontally is Romeo from the
balcony?

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.
