A particle of mass 2 kg experiences two forces `verF = 5 hati + 8 hatj + 7 hatk and vecF _2 = 3 hati - 4hatj + 3hatk ` What is the acceleration of the particle?

Explanation

We use Newton.s second law, `vecF_(n e t) = m veca `where `vecF = vecF_(1) + vecF _2 ` From the equations the acceleration is `veca = ( vecF _(n e t))/(m)`, where
` vecF _(n et) = ( 5+ 3 ) hati +(8 - 4) hatj (7+3) hatk`
` vecF_(n e t) = 8 hati + 4 hatj + 10 hatk `
` veca = ((8 ) /(2) ) hati +((4)/(2)) hatj +((10)/( 2)) hatk `
` vec a = 4 hati + 2hatj + 5 hatk `
