dayshawn is traveling at 12 m/s away from the school. dayshaun's mom is looking for him because he is late coming home so she left the house and is driving toward the school at 5 m/s. The school is 6492 m from dayshauns house. at what position will dayshawn meet his mom and how long after she left the house did she find dayshaun? draw a motion map and solve. show your work
Answers
Speed of Dayshawn travelling towards his home is 12 m/s
Speed of her mom towards his school is 5 m/s
They both starts at same time so whenever they will meet on their path the sum of the distance covered by Dayshawn and distance covered by his mom must be equal to the total distance of school and home
Now let say they both meet after "t" time when they starts motion
so we can write the total distance between school and home as
here d = 6492 m
= speed of dayshawn
= speed of his mom
now by solving the above equation
so they will meet after 381.9 s from start which will be 3.36 minutes from there start
Also at this time the distance covered by her mom will be
so they will meet at distance 1909.4 m from their home

Weight = (mass) x (gravity)
Weight = (100kg) x (9.8 m/s^2)
Weight = 980 kg-m/s^2
Weight = 980 Newtons.
(about 220.5 pounds)
Final answer:
The weight of a 100 kg mass on Earth's surface is 980 Newtons(N). This is calculated using the formula 'w=mg', where 'w' is weight, 'm' is mass, and 'g' is the acceleration due to gravity on Earth (9.80 m/s²).
Explanation:
On earth, the weight of an object is determined by the gravitational force acting on it. This can be calculated using the formula w = mg, where 'w' is the weight of the object, 'm' is its mass, and 'g' is the acceleration due to gravity on Earth. Given that the mass 'm' is 100 kg and the acceleration due to gravity 'g' on Earth's surface is approximately 9.80 m/s², we can determine the weight of the object by substituting these values into the formula.
Applying these values into our equation, we get: w = (100 kg)(9.80 m/s²) = 980 N. Therefore, a 100 kg mass weighs 980 Newtons (N) on Earth's surface.
It is pertinent to note that an object's weight can vary based on its location as the value of 'g' changes with location. For instance, the value of 'g' on the moon is only about 1.67 m/s², which is far less compared to Earth, resulting in a lighter weight for the same mass.

There would be no motion,as the object get stuck
Answer:
Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.
