A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction
A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction. Both of these pieces fly away with a speed of V = 35 m/s. The third piece has three times the mass of the other two pieces. Part (a) Write an expression for the speed of the larger piece, that is in terms of only the variable V. Part (b) What is the numeric value for...

1-3 please
Ken, a 46 ylo male who works as a carpenter, was admitted to the ED after having a grand ma seizure while at a construction site. At this time, Ken is unconscious but breathing on his own and no farther seizure activity is noted. His co-worker stated that Ken fell off a ladder a year and a half ago and he suffered a severe coneussion, however, he has had no further complications since recovering from that injury. An...
