An object has a kinetic energy of 275 j and a momentum of magnitude 25.0 kg · m/s. find the (a) speed and (b) mass of the object.

The correct answers are 482.4 m/s and 21.96 kg.

Explanation:

The expression for the kinetic energy in terms of momentum of an object is as follows;

Here, KE is the kinetic energy, p is the momentum and m is the mass of the object.

It is given in the problem that an object has a kinetic energy of 275 j and a momentum of magnitude 25.0 kg · m/s.

Calculate the mass of the object.

Put p=25.0 kg · m/s and KE= 275 J.

Calculate the speed of the object.

Put m= 1.14 kg and KE= 275 J.

v=21.96 m/s

Therefore, the speed of the object is 21.96 m/s and the mass of the object is 1.14 kg.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
