Question

This is a sequential question. The first three parts have been answered. Please kindly help solve the last one (d)

A)
B)
You are sitting in a sled, at rest on a pond covered with
nice, thick, frictionless ice. Your own mass is 77.2 kg, and
the mass of the sled when empty is 14.3 kg. From shore,
someone throws a baseball of mass 0.125 kg to you, and
you catch it; the horizontal component of the ball s
velocity is 28.2 m/s. What will be the sled s (and your)
speed with respect to the surface of the pond after you
This time, your mass is 81.2 kg and the sled s mass is
12.0 kg. You re on the sled, initially moving to the west at
5.14 cm/s. From the southern shore, your friend throws a
baseball of mass 0.189 kg, which you catch as it s
traveling northward with a horizontal velocity component
of 29.3 m/s. What will be the sled s (and your) speed after
catching the ball?
