Explanation:
I'm pretty sure this is correct
Answer:
Option C. 1.2 m
Explanation:
The following data were obtained from the question:
horizontal velocity (u) = 2.08 m/s
Horizontal distance (s) = 0.96 m
Height (h) of the table =?
Next, we shall determine the time taken for the lab cart to get to the ground. This can be obtained as follow:
horizontal velocity (u) = 2.08 m/s
Horizontal distance (s) = 0.96 m
Time (t) =?
s = ut
0.96 = 2.08 × t
Divide both side by 2.08
t = 0.96 / 2.08
t = 0.5 s
Finally, we shall determine the height of the table as illustrated below:
Time (t) = 0.5 s
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) of the table =?
h = ½gt²
h = ½× 9.8 × 0.5²
h = 4.9 × 0.25
h = 1.2 m
Thus, the height of the table is 1.2 m
There are mistakes in the question as the unit of speed and height is not mention here.The correct question is here
A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 16.0m/s when the hand is 1.80m above the ground.How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.)
Answer:
t=3.37s
Explanation:
Given Data
As we have taken hand at origin and positive upward
So given data are
To find
time taken by the ball before it hits the ground
Solution
By using the common kinematic equation
Put the given values and find for t
So
Apply quadratic formula to solve for t
