2 balls have masses of 50 gm and 100 gm and they are moving along the same line in the same direction with velocites of 3 m/s and 1.5 m/s respectively. They collide with each other and after the collision, the first ball moves with a velocity of 2.5 m/s.Calculate the velocity of the other ball after collision.
Answers
Given:
The mass of first ball = m 1 = 50 g = 0.05 kg
The mass of the second ball = m 2 = 100 g = 0.1 kg
Initial velocity of the first ball = u 1 = 3 m/s
Initial velocity of the second ball = u2 = 1.5 m/s
Final velocity of the first ball = v 1 = 2.5 m/s
To find:
Final velocity of the second ball = v 2 = ?
We know that, total initial momentum = Total final momentum.
= m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2
= (0.05 × 3) + (0.1 × 1.5) = (0.05 × 2.5) + (0.1 × v 2 )
= (0.15)+(0.15) = 0.125 + 0.1v2
= 0.3 = 0.125 + 0.1 v 2
= 0.1v 2 = 0.3 - 0.125
= v2 = 0.175/0.1
= 1.75 m/s
Therefore, Velocity of Ball after collision is 1.75m/s.
Answer:
Velocity of Ball after collision is 1.75m/s.
Explanation:
Given:
The mass of first ball = m 1 = 50 g = 0.05 kg
The mass of the second ball = m 2 = 100 g = 0.1 kg
Initial velocity of the first ball = u 1 = 3 m/s
Initial velocity of the second ball = u2 = 1.5 m/s
Final velocity of the first ball = v 1 = 2.5 m/s
To find:
Final velocity of the second ball = v 2 = ?
We know that, total initial momentum = Total final momentum.
= m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2
= (0.05 × 3) + (0.1 × 1.5) = (0.05 × 2.5) + (0.1 × v 2 )
= (0.15)+(0.15) = 0.125 + 0.1v2
= 0.3 = 0.125 + 0.1 v 2
= 0.1v 2 = 0.3 - 0.125
= v2 = 0.175/0.1
= 1.75 m/s
pace is the directional velocity of a object in motion as a demonstration of its charge of trade in role as observed from a selected frame of reference and as measured through a selected widespread of time (e.g. 60 km/h northbound).[1] velocity is a essential concept in kinematics, the branch of classical mechanics that describes the motion of our bodies.
velocity is a physical vector quantity; each importance and route are needed to define it. The scalar absolute cost (value) of velocity is known as pace, being a coherent derived unit whose quantity is measured within the SI (metric system) as metres in keeping with second (m/s or m⋅s−1). as an example, "5 metres consistent with 2d" is a scalar, while "5 metres consistent with 2d east" is a vector. If there may be a alternate in pace, route or each, then the item is said to be undergoing an acceleration.
