Question

from the tower of height 900 object is dropped after 2 second dropping a another object based dropped with velocity 2 metre per second find the time taken by b to hit the ground and weather object crosses a or not find the final velocity
of both ​

Answer 1

Answer:

this is hind for you

Step-by-step explanation:

Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.

Answer 2

Answer:

Step-by-step explanation:

S=900m

T=2s

U=2m/s

S=ut+1/2at^2

900 =2*2+1/2a4

900=4+2a

a=896/2

a=448

Now,

V=u+at

V=2+448*2

V=898m/s
