Imagine a pizza, the pizza is cut into 4 slices and 2 have already been eaten. There you go! You now have the fraction 2/4. 2/4=1/2. 1/2 as a percentage is 50%.
Answer:
Option 2. 1.4 seconds
Step-by-step explanation:
As we know when a ball is dropped from a height then we apply the formula
Here h = height from the ground
u = initial speed of the ball
t = time taken to reach the ground
g = acceleration due to gravity
Now we put the values of these parameters
h = 30 feet ≅ 9.144 met.
u = 0
g = 9.8 met/sec²
9.144 = 0 + 1/2×9.8×t²
9.144 = 4.9×t²
t² = 9.144÷4.9
t² = 1.87
t = 1.37 ≅ 1.4 seconds
Therefore option 2 is the answer.
