Part a)
in horizontal direction there is no gravity or no other acceleration
so in horizontal direction the speed of clam will remain same
Part b)
In vertical direction we can use kinematics
part c)
if the speed of crow will be increased then the horizontal speed of the clam will also increase but there is no change in the vertical speed
Using the precise speed of light in a vacuum (
), and your given distance of 
, we can convert and cancel units to find the answer. The distance in m, using 
, is 
. Next, for the speed of light, we convert from s to min, using 
, so we divide the speed of light by 60. Finally, dividing the distance between the Sun and Venus by the speed of light in km per min, we find that it is 6.405 min.
A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion
<h3>Further explanation </h3>In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero, it can be formulated :
then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called<em> inertia </em>
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass m that move translatively, the object will maintain its linear velocity
When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.
