A crow is flying horizontally with a constant speed of 2.45 m/s when it releases a clam from its beak. The clam lands on the rocky beach 2.30 s later. Consider the moment just before the clam lands. (Neglect air resistance.)

a)What is its horizontal component of velocity? (in m/s)
(b) What is its vertical component of velocity? (in m/s)

Question

A crow is flying horizontally with a constant speed of 2.45 m/s when it releases a clam from its beak. The clam lands on the rocky beach 2.30 s later. Consider the moment just before the clam lands. (Neglect air resistance.)

a)What is its horizontal component of velocity? (in m/s)
(b) What is its vertical component of velocity? (in m/s)

matt101 · Answer

Neglecting air resistance, the horizontal velocity will not have changed (i.e. it remains 2.45 m/s).

The vertical velocity starts at 0 m/s and accelerates for 2.30 s (due to gravity).

9.8 = (x-0)/2.3
x = 22.54

Therefore your vertical velocity is 22.54 m/s.

anonymous · Answer

a) It would remain the same, because there is no force, and thus acceleration, in that direction. So, it would just be 2.45 m/s.
b) Use$$ v=v_{0}+at$$
Because $$ v_{0}$$=0 in the y direction, it is just
v=at
It said that t=2.3 s, and a=9.8. Plug that in...
v=2.3*9.8=22.54 m/s
