A body of mass 100g moving with a velocity of 10.0m/s collides with a wall .if after the collision it moves with a velocity of 2
.0m/s in the opposite direction,calculate the change in momentum
1 answer:
Answer:
-1.2 kg - m/s
Explanation:
And we need to find out the change in momentum of the body . Here ,
- velocity before collision (u) = 10m/s
- velocity after collision (v) = 2m/s .
We know that momentum is defined as amount of motion contained in a body . Mathematically ,
Therefore change in momentum will be,
Since the direction of velocity changes after the collision , the velocity will be -2m/s .

Its the answer of B speed and velocity
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Why are you still having a problem with F = M · a ?
Answer:
1.7 L
Explanation:
PV = nRT
If P, n, and R are constant:
V₁ / T₁ = V₂ / T₂
(2.0 L) / (293.15 K) = V / (255.15 K)
V = 1.7 L
Sound waves are a type of classical waves and so they transport only energy without transporting matter through the medium.
