Here, Apply 2nd equation of the Kinematics :
S = ut + 1/2 at²
Here, s = 60 m
u = 0 [ free fall ]
a = 9.8 m/s² [ constant value for Earth system ]
Substitute their values,
60 = 0*t + 1/2 * 9.8 * t²
120 = 9.8t²
t² = 120 / 9.8
t = √12.24
t = 3.50 s
In short, Your Answer would be 3.50 seconds
Hope this helps!

In physics<span>, a </span>force<span> is said to do </span>work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). so in the proble, <span>She does NO work since the force she applies to the case is vertical and the direction of motion is horizontal. Work is the force times the parallel distance</span>
Answer: They include elements 57-71, or lanthanides, and 89-103, or actinides. ... Inner transition metals have three incomplete outermost electron shells and are all metals.
