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 roc
ky 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)
<span>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. </span>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<span>v=<span>v0</span>+at</span>
Because <span>v0</span><span>=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</span>
