Answer:
The speed of the object is 20.24 m/s.
Explanation:
For a body of mass 'm' travelling with velocity 'v' , its kinetic energy is gievn by -
[tex]KE = \frac{1}{2}mv^{2}[/tex] --- 1
The momentum of body is given by -
[tex]p = mv[/tex] ---- 2
Dividing equation 1 and 2 , we get -
[tex]\frac{KE}{p} = \frac{v}{2}[/tex]
Given that ,
KE = 249 J
p = 24.6 kg.m/s
Substituting the 2 values in the above equation , we get -
v = 20.24 m/s.
