Question

Three forces Fi = (2 +43) N: F2 = 12) - K)N
and 5 =(k-4-2)) N are applied on an object of
mass 1 kg at rest at origin. The position of the
object at t = 2 s will be​

Answer 1

Explanation:

• Fnet= 2i+4j+2j-k+k-4i-2j
• -2i+6j
• -2i+6j
• anet =-2i+6j
• S= 1/2 at2=1/2*a*4 =2a
• Si=2(-2) = - 4
• Sj= 2(6)=6
• S=-4i+6j
