A particle of mass 2 kg experiences two forces, `vecP_1 = O , vecP_2 = O " and " vecF_2 = 3 hati - 4hatj + 3hatk ` . What is the acceleration of the particle?

Explanation

We use Newton.s second law, `vecF_("net") = m vec a ` From the above equations the acceleration is `vec a = (vecF_("net"))/(m) ` where
` vecF_("net") = (5 + 3) hati + (8 -4) hatj + (7 +3) hatk `
`vecF = 8hati + 4 hatj + 10 hatk `
` vec a =(8/2) hati (4/2) hatj + (10/2) hatk `
` vec a = 4hati + 2 hatj + 5hatk `
