Answer:
0.48 kgm/s
Explanation:
= mass of the particle = 2.43 μg = 2.43 x 10⁻⁶ x 10⁻³ kg = 2.43 x 10⁻⁹ kg
= velocity of the particle = 1.97 x 10⁸ m/s
= momentum of the particle
momentum of the particle is given as
inserting the values
kgm/s
Answer:
Velocity will be equal to 7.31 m/sec
Explanation:
We have given mass of the student m = 61 kg
Height of the water slide h = 12.3 m
Acceleration due to gravity
Potential energy is equal to
Work done due to friction = -5800 J
So energy remained = 7352.94-5800 = 1552.94 J
This energy will be equal to kinetic energy
So
v = 7.13 m/sec
Answer:
0.90291 m/s
0.45055 m/s
Explanation:
= Mass of canon = 2090 kg
= Mass of ball = 16.7 kg
= Velocity of canon
= Velocity of ball = 113 m/s
In this system the momentum is conserved
The velocity of the cannon is 0.90291 m/s
Applying energy conservation
The ball would travel 113.45055-113 = 0.45055 m/s faster
