Whats the velocity if a seagull drops a shell from rest at a height of 11m, how fast is the shell moving when it hits the rocks

Seagull is at height 11 m

it drops a shell from rest

so here we know that

acceleration of shell is due to free fall = -9.81 m/s^2

displacement = - 11 m

initial speed = 0

now we will use kinematics equation here in order to find the final speed

now plug in all values in it

so here the speed by which shell will strike with the rocks is 14.7 m/s

seeing the graph would

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
