On an object of mass 1kg moving along x-axis with constant speed 8m/s a constant force 2N is applied in positive y-direction.Find its speed after 4 seconds.?

Question

Debdeep · Answer

Velocity along x=8(constant) Acceleration along y=2m/s^2Velocity along y after 4 s=2*4=8m/sSpeed =8/2m/s

Deligant · Answer

Mass=1kg. Velocity= 8i^. Force=2j^. F= ma so. 2j^=1.v-u/t. = v-8i^/4. So 8j^+8i^=v. Since he is asking the magnitude. ​ root over 8 2+ 8 2 =8root 2
