Answer:
Explanation:
initial velocity
magnitude of velocity, v = 12 m/s
angle made of velocity with negative x-axis,θ = 60°
We need to calculate x- component of v
velocity is in negative x-direction, v = -12 m/s
now,
Hence, the velocity x-component is equal to -6 m/s.
Answer:
2d
Explanation:
For any instance equivalent force acting on the body is
Where
m is the mass of the object
k is the force constant of the spring
d is the extension in the spring
and
d/dt(dx/dt)= is the acceleration of the object
solving the above equation we get
where
A is the amplitude of oscillation from the mean position.
k= spring constant , T= time period
Here we are assuming that at t=T/4
x= 0 since, no extension in the spring
then
A=- d
Hence
x=- d sin wt + d
now, x is maximum when sin wt=- 1
Therefore,
x(maximum)=2d
