Answer:
The maximum displacement of the mass m₂
Explanation:
Kinetic Energy (K) = 1/2mv²
Potential Energy (P) = mgh
Law of Conservation of energy states that total energy of the system remains constant.
i.e; Total energy before collision = Total energy after collision
This implies that: the gravitational potential energy lost by m₁ must be equal to sum of gravitational energy gained by m₂ and the elastic potential energy stored in the spring.
d = maximum displacement of the mass m₂
Answer:
17.284 rad/s^2
Explanation:
F = 337 N
R = 0.398 m
M = 98 kg
let the angular acceleration is α
torque = I x α = F x R
Where I is the moment of inertia
I = 1/2 MR^2 = 0.5 x 98 x 0.398 x 0.398 = 7.76 kg m^2
So,
7.76 x α = 337 x 0.398
α = 17.284 rad/s^2
Answer:
V=14
Explanation:
PE=KE
mgh=1/2mv^2
(2)(9.8)(10)=1/2(2)v^2
(radical) 196=(radical) v
V=14
