- A block of mass m = 1.34 kg (Block 1) at rest at Point A on an arc of smooth circular surface of radius L = 30 m. Another block of mass M = 3.22 kg (Block 2) is at the bottom of the arc as shown in Fig.6. The line between the center of the arc and Point A and the line between the center of the arc and Point B make an angle 0 = 35 deg. If Block 1 is released and slides on the arc and hits Block 2, Block 1 stops at Point B and Block 2 starts to move along the arc. What is the velocity of Block B right after the collision in m/s. Keep three significant figures for the answer. g= 9.80 m/s. There is no friction.3) The meaning of the word "WORK" is quite different in physics from its everyday usage. Give an example of an action a person could do that "feels like work" but that does not involve any work as we've defined in this chapter. Support your reasoning with equations/data.Will rate!!
