A 204-kg projectile, fired with a speed of 131 m/sat a 65.0
∘ angle, breaks into three pieces of equal mass at the
highest point of its arc (where its velocity is horizontal). Two of
the fragments move with the same speed right after the explosion as
the entire projectile had just before the explosion; one of these
moves vertically downward and the other horizontally.
A. Determine the magnitude of the velocity of the third fragment
immediately after the explosion.
B....

The diagram below shows a block of mass m=2.00kgm=2.00kg on a
frictionless horizontal surface, as seen from above. Three forces
of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and
F3=8.00NF3=8.00N are applied to the block, initially at rest on the
surface, at angles shown on the diagram. (Figure 1) In this
problem, you will determine the resultant (total) force vector from
the combination of the three individual force vectors. All angles
should be measured counterclockwise from the positive x
axis (i.e., all angles are...
