Question

a student throws a ball vertically downwards with 6m/s
a) what is the speed after falling for 2 seconds?
b) how far does it travel in 2 seconds?
c) what is the velocity after falling 10m​

Answer 1

Answer:

hlo dear

Explanation:

here u are

v= u+at

now we will use a=g

so v= u+gt

after 2 second its speed will be

v= 6+ 9.8×2

v= 19.6+6 = 25.6

v=25.6

s= ut+1/2 gt²

so

s= 12+19.6 = 31.6 m

here u are
