The largest frog ever found was discovered in Cameroon in 1989.
The frog's mass was nearly 3.6 kg. Suppose this frog is placed on a
skateboard with a mass of 3.0 kg. The frog jumps horizontally off
the skateboard to the right, and the skateboard rolls freely in the
opposite direction with a speed of 2.0 m/s relative to the ground.
If the frog and skateboard are initially at rest, what is the initial
horizontal velocity of the frog? Round to the hundredths.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
