Answer:
7.59Ns
Explanation:
Given parameters:
Force = 1360N
Time of contact = 5.85 x 10⁻³s
Unknown:
Impulse = ?
Solution:
The impulse of the ball is given as:
Impulse = Force x time
Impulse = 1360 x 5.85 x 10⁻³ = 7.59Ns
States of matter can change through temperature
For example
Cold: Ice
Medium: Water
Hot: Steam
Pressure can change the temperatures at which the matter changes state
Answer:
15 m
Explanation:
Given,
Mass ( m ) = 75 kg
Potential energy ( P.E ) = 11,025 J
To find : Hight ( h )
Formula : -
P.E = mgh
[ Note : The value of g = 9.8 m/s² ]
h = P.E / mg
= 11,025 / ( 75 x 9.8 )
= 11,025 / 735
h = 15 m
Hence,
15 m is the high off the ground must you be if you mass is 75 kg and you have 11,025 J of energy stored inside.
