Michelle drops a 15kg box off of the Eiffel Tower. After 3 seconds, how fast is the box moving in m/s? (Neglect air resistance.)

i don’t know what the answer is i wish i

a.   mass number from atomic number

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

prndulum needs thread, weight clock to time swings
