Answer:
Mass = 1350kg
Explanation:
Given the following data;
Velocity = 23m/s
Momentum = 31,050 kg·m/s.
To find the mass of car;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the equation, we have
31,050 = mass*23
Mass = 31,050/23
Mass = 1350kg
Therefore, the mass of the car is 1350 kilograms.
Use Newton's 2nd law of motion.
Here it is:
Force = (mass) x (acceleration)
= (80 kg) x (-5 m/s²)
= -400 Newtons .
I called the acceleration negative because the player is slowing down.
The force comes out negative because it's in the direction opposite to
his motion.
The answer is diffraction or interference
Answer:
i needed points it was an emergency sorry
Explanation:
Answer:
It will take 2.68 minutes for them to reach each other.
Explanation:
We use the two following kinematic equations, making the final position the same (for the moment they meet each other):
locomotive 1 --> 
locomotive 2 --> 
we make the two xf equal, and solve for the time (t) using v = 95 km/h:
converting the hours into minutes by multiplying this value times 60;
t = 2.68 minutes
