Question

a body of mass 5 kg is acted upon by two perpendicular forces 8n and 6n find the magnitude and direction the acceleration

Answer 1

Hope it will help you!

Answer 2

Answer:

Net force, F 2=82+62 N

F2=100 N and hence, F= 10N

Acceleration, a = F/m= 10/5= 2m/s2

If the net force F makes an angle beta(b) with the horizontal, then the acceleration will also make an angle beta (b) with the horizontal . this is because the acceleration is always in the direction of force.

Tan b =6/8 =3/4 = 0.75

Hence, b = tan-1(0.75)= 36.9°
