1) alpha particle, the element Radium undergoes alpha decay, releasing an alpha particle.
Answer: 53125joules
Explanation: The formula for kinetic energy is 1/2mv^2.
So we would have
1/2[(170)(25x25)]=53125
b.
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
