Answer:
At the lowest point in the oscillation, the momentum is zero.
At the lowest point in the oscillation, 
Explanation:
Since spring block system is performing to and fro motion along straight line
So here we can say at the lowest position of its path the velocity will become zero.
So we can say that momentum of the spring block system is given as
Also we know that after reaching the lowest point the block will again go up towards its mean position
So at the lowest point of the spring block system the block will move upwards again
So this will accelerate upwards hence
Lungs vacoules on if those 2
Answer:
sorry
Explanation:
i don't know this but when i find the answer i will type here
The acceleration produced in a body is always in the direction of the resultant force acting on the body. Therefore, we may determine the horizontal acceleration using the horizontal force applied. To do this, we may apply the mathematical form of Newton's second law:
Force = mass * acceleration
acceleration = force / mass
Substituting the values,
a = 100 / 0.15
a = 666.7 m/s²
The acceleration of the hockey puck is 670 m/s²
Answer:
(a) 67.44 second
(b) 529.5 revolutions
Explanation:
ωo = 49.3 rad/s
α = 0.731 rad/s^2
(a) Let it takes t time to come to rest.
ω = 0
Use first equation of motion for rotational motion
ω = ωo + α t
0 = 49.3 - 0.731 x t
t = 67.44 second
(b) Let it turns an angle θ rad before coming to rest. use third equation of motion for rotational motion.
ω^2 = ωo^2 + 2 α θ
0 = 49.3 x 49.3 - 2 x 0.731 x θ
2430.49 = 1.462 θ
θ = 1662.44 rad
Number of revolutions = θ / 2π = 1662.44 / 3.14 = 529.5 revolutions
