Three liquids are at temperatures of 8°C, 20°C, and 30°C, respectively. Equal masses of
the first two liquids are mixed, and the equi-
librium temperature is 14°C. Equal masses of
the second and third are then mixed, and the
equilibrium temperature is 26.5°C.
Find the equilibrium temperature when
equal masses of the first and third are mixed.
Answer in units of C.

he kicked it 10 feet straight up into the air? i think this works.

its a 5.5 n

glad that

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

80cm/s.

24cm/s.

53.3cm/s.
