A square metal plate of mass 5 kg, side length 1 m, and uniform density has a 1 kg mass placed on one corner and a 2 kg mass placed on an adjacent corner. What is the distance between the 1 kg point mass and the center of mass of the system?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Ithink it's  c. i'm sure 

Motion i think. hope it
