1.1 A small steel ball moves in a vertical circle in a
counter-clockwise direction with an angular velocity of 4
radians/s. with a radius of 2.50 m at a time t = 0 s. The
shadow of this steel ball is at +1.00 m in the X-axis and is moving
to the right.
a) Find xt) indicating its position. (SI units)
b) Find the velocity and acceleration in the X-axis as a
function of the time of this shadow.
1.2 Mass 100 g is attached to the tip of an aerated spring with
spring constant. 20.0 Nm, then this mass is taken out at a
distance of 10.00 cm from the equilibrium point. and released
from standstill
a) Find the period of vibration
b) What is the magnitude of the greatest acceleration of
this mass? and where does it occur?
c) What is the greatest velocity of this mass?
d) Write the equation of motion as a function of time in SI
to express position (t), velocity V(t), and acceleration a(t)
