To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,
Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.
Replacing,
The height of the acorn above the meter stick can be calculated as,
Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
So, her kinetic energy right before she hits the water is equal to 2450 J.
If two people are standing in different locations the length of the line is a measurement of distance
Answer:
t = 12.82s
Explanation:
F = m×a
= (70)×(2)
= 140 N
during the acceleration, the sprinter cover d = 29 m with time:
d = 1/2×at
29 = 1/2×(2)×t^2
t^2 = 29s
t = 5.39s
and attains the velocity of:
v = a×t
= 2×5.39
= 10.77 m/s
Then,to cover the last x = 80 m with a speed of 10.77 m/s in time:
t = x/v
= 80/10.77
= 7.43s
Therefore, it will take the sprinter 7.43 + 5.39 = 12.82s
Answer:A skier could benefit from a sports-specific training program because it could help them become better at skiing. ... Other activities such as squats and lunges will also improve skiing skills since it builds up lower body strength which is necessary to ski tough terrain.
Explanation:
