Answer:
flattened by pressure; squeezed or pressed together.
Explanation:
Answer:
The velocity with which the jumper strike the mat in the landing area is 6.26 m/s.
Explanation:
It is given that,
A high jumper jumps over a bar that is 2 m above the mat, h = 2 m
We need to find the velocity with which the jumper strike the mat in the landing area. It is a case of conservation of energy. let v is the velocity. it is given by :

g is acceleration due to gravity

v = 6.26 m/s
So, the velocity with which the jumper strike the mat in the landing area is 6.26 m/s. Hence, this is the required solution.
To find the mass of the planet we will apply the relationship of the given circumference of the planet with the given data and thus find the radius of the planet. From the kinematic equations of motion we will find the gravitational acceleration of the planet, and under the description of this value by Newton's laws the mass of the planet, that is,
The circumference of the planet is,

Under the mathematical value the radius would be



Using second equation of motion

Replacing the values given,

Rearranging and solving for 'a' we have,

Using the value of acceleration due to gravity from Newton's law we have that

Here,
r = Radius of the planet
G = Gravitational Universal constant
M = Mass of the Planet


Therefore the mass of this planet is 
Answer:
Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
Explanation:
Speed is the ratio of distance and time and velocity is the ratio of displacement and time.
Distance traveled = 10 + 5 = 15 cm = 0.15 m
Displacement = 10 - 5 = 5 cm = 0.05 m
Time = 20 seconds

Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
Sorry if im wrong but I'll say kinetic energy
Hope it helps:)
