Please help me solve this​

Answer 1

Following are the solution to this question:

Step-by-step explanation:

`\to \Sigma F_x = ma_x \\\\\to 3200 t^2 -440 (9.81) ((8)/(17)) = 440 (a) \\\\\to 3200 t^2 -2031.24 = 440 (a)\\\\\to a= 7.27t^2 -4.616\\\\\to dv=a.dt \\\\\to \int^(v)_(2) dv = \int^(2)_(0) (7.27t^2 -4.616) dt\\\\\to v-2 = 7.27 (t^3)/(3) - 4.616 t^(2)_(0)\\\\\to v-2 = 7.27 (2^3)/(3) - 4.616 {2} \\\\\to v-2 = 10.154\\\\\to v= 12.154 \ (m)/(s)\\`
