An object is dropped from a platform 100 feet high. ignoring wind resistance, how long will it take to reach the ground? s a 1.8 b 2.5 c 3.2 d 4.5

Height of the platform = 100 feet

1 feet = 0.3048 m

100 feet = 30.48 m

Acceleration due to gravity (g) = 9.8 m/s^2

Let the time taken be t

Initial velocity of the object (u) = 0 m/s

Using the seconds equation of motion:

t = 2.5 seconds

Hence, the option (b) is correct.

what is the question?

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb
