2. A father pulls a child on a sled across the snow, as shown in Figure 2.28a. The child and sled have a combined mass of 50 kg. If the snow has a coefficient of kinetic friction of 0.23 and the father applies a force of 200 N along the handle of the sled 30 above the horizontal, determine the acceleration of the child and sled. [1.3 mfszh'igh]. 3. Mr. W'harf accidentally fires two rockets on his shuttlecraft at the same time. The first rocket applies a force of 1000 N [E25S], and the second rocket applies a force of 1200 N [N40'W]. If the shuttlecraft has a mass of 5.0 X 104kg, determine the vector acceleration it will experience. [11] X 10'2m1'52 [E75N]
