The net force will point towards the acceleration of the object, as supported by Newton's second law.
Answer:
14700 J
Explanation:
The gravitational potential energy of an object is given by:
where
m is the mass
g is the gravitational acceleration
h is the height of the object above the ground
In this problem:
m = 50 kg is the mass of the hiker
h = 30 m is the heigth of the cliff
Substituting, we find
Answer:
To write a number in scientific notation. First write a decimal point in the numbers so that there's only one digit to the left of the decimal point.
Narrow tires bikes are used in racing competitions.
Bikes that have narrow tires are used in race because narrow tires have an advantage over wider tires due to their higher speed as they provide less air resistance. Less air resistance on the bike having narrow tires allows the bike to move faster as compared to those bikes having wider tires due to more air resistance so we can conclude that bikes with narrow tires are used in racing competitions.
