Answer:
9.21954 m/s
54 m/s²
Angle is zero
Explanation:
r = Radius of arm = 1.5 m
= Angular velocity = 6 rad/s
The horizontal component of speed is given by
The vertical component of speed is given by
The resultant of the two components will give us the velocity of hammer with respect to the ground
The velocity of hammer relative to the ground is 9.21954 m/s
Acceleration in the vertical component is zero
Net acceleration is given by
Net acceleration is 54 m/s²
As the acceleration is towards the center the angle is zero.
