Apilot flying low and slow drops a weight; it takes 2.0 s to hit the ground, during which it travels a horizontal distance of 190 m . now the pilot does a run at the same height but twice the speed. how much time does it take the weight to hit the ground?

time taken by the object dropped = 2s

this time depends on the height of the plane from ground

it is given by

now the distance covered horizontally is given as 190 m

now the speed of the object is

now when plane is moving at same height but with double speed

so it will take same time to hit the ground again

so the time is given as

so it will take t = 2 s again to hit the ground

f is prop to m1xm2 double m1 double force

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
