Answer:
56 kg
Explanation:
The change in potential energy of the man is given by:
where
m is the man's mass
g is the gravitational acceleration
is the change in height of the man
In this problem, we have:
is the gain in potential energy
g = 9.8 m/s^2 is the gravitational acceleration
is the change in height
Re-arranging the equation and substituting the numbers, we find the mass:
Answer:
distance, x = 38.17 m
Given:
velocity of the football, v = 20.5 m/s
football projected at an angle,
Period of flight, T = 2.15 s
Therefore, the distance covered by the football, x is given by:

In maltreatment rate, children of ages 16 to 17 are lower than the children ages 0 to 3.
The rate of maltreatment of smaller children is 3 times higher than bigger ones
Answer:
Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.
