Answer:
41.13m
Explanation:
Given parameters:
Initial velocity = 4.2m/s
Time taken = 2.5s
Unknown:
height of the platform = ?
Solution:
To solve this problem, we must use the appropriate motion equation.
S = ut + [tex]\frac{1}{2}[/tex]gt²
u is the initial velocity
t is the time
g is the acceleration due to gravity
Now, input the parameters and solve;
S = (4.2x2.5) + ( [tex]\frac{1}{2}[/tex]x 9.8 x 2.5²)
S = 41.13m
