Answer:
2.22 m
Explanation:
According to literature, the highest abrupt deceleration the human body can experience and survive in a car accident is 250 m/s²
Using the equations of motion,
v² = u² + 2as
v = final velocity of the body = 0 m/s
u = initial velocity of the body = 120 km/h = 120 × 1000/3600 = 33.33 m/s
a = - 250 m/s²
s = ?
0² = 33.33² - (2×250×s)
500s = 1111.1111
s = 2.22 m
Answer:
A prism is a piece of glass or plastic in the shape of a triangle.
Explanation:
The colors of the rainbow in order are: red, orange, yellow, green, blue, indigo, and violet.
Answer:
If you use the same force to push a truck and a car, the car will have more acceleration than the truck because the car has less mass.
It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the shopping cart.
When a person kicks a ball the person exerts force in a specific direction, that is the direction in which it will travel. In addition to this, the stronger the ball is kicked, the stronger the force we put on it and the further away it will travel.
Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
When riding a bicycle, the bicycle acts as mass and our leg muscles pushing on the pedals of the bicycle is the force.
Explanation:
Answer:
66.6 kg
Explanation:
The weight of a person at Earth's surface is given by
where
m is the mass of the person
is the acceleration of gravity
The person in the problem has a weight of
W = 653 N
Therefore, we can rearrange the equation to find his mass:
