Since distance is a scalar and not a vector, the total distance traveled is the sum of all the distances covered throughout the journey.
In Physics, we have two categories of quantities;
The difference between vectors and scalars is that vectors has direction but scalars do not have direction. Both quantities posses magnitude.
The total distance covered can be obtained algebraically since distance is a scalar.
Hence, total distance covered = 2 cm + 6cm + 5 cm = 13 cm

Force of friction=75 N
Explanation:
we use Newton's second law of motion
F- Ff= ma
F = applied force=250 N
Ff= force of friction
a= acceleration= 5.83 m/s²
m= mass=30 kg
250- Ff= 30 (5.83)
Ff=250-30(5.83)
Ff=250-175
Ff=75 N
Answer:
2 x 2 x 2 x 3 x 7 = 168
Explanation:
Prime factors of 168: 2, 3 and 7
These are the factors of 168: 1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168. Only 2, 3 and 7 are prime numbers meaning that they are only divisible by themselves and 1. Therefore they are the prime factors.
If your mass is 140kg , then your mass is <em>140kg</em>.
It doesn't make a bit of difference what time it is, whether you're happy or sad, sleeping or lifting weights or running, whether it's raining or shining, hot or cold, climbing a mountain or falling out of an airplane, on the surface of a planet, asteroid, comet or star, or floating or falling through empty lonely outer space. Your mass is your mass. The only way it can change is if YOU make changes in yourSELF, like eating a big steak, sweating through a long tough workout, or skipping dinner, or growing to maturity.
(I guess you're already pretty mature. If your mass is 140kg, then you weigh about 308 pounds when you're on Earth.)
The magnitude of v⃗ is {sqrt(m1v1)2+(m2v2)2/ m1+m2}, that is, the speed v of the two-car unit after the collision.
<h3>What is
collision?</h3>
- In physics, collisions occur when particles, aggregates of particles, or solids come close to each other, interact and affect each other.
- Collisions are of three types Fully elastic collision, inelastic collision and Perfectly inelastic collision.
- Multiply the mass of the second object by its velocity.
- For example, if the weight is 1,000 and the speed is -30 meters per second, then its momentum is 30,000 kg meters per second.
- Add the two velocities together to determine the direction the object will move after a collision.
- So the formula for determining the size of a vector (in 2D space) is v = (x, y).|v| = √(x2 + y2).
- This formula is derived from the Pythagorean theorem.
- The formula V = (x, y, z) that determines the size of a vector (in 3-dimensional space) is:|V| = √(x2 + y2 + z2)
