Question

a cricket ball reaches from M to N after successive displacement calculate the total displacement, given Sin 37 degree equal to 0.60 and Cos 37 degree equal to 0.80

Answer 1

From above, we can take all the vectors at a point m and resolve the values along X and Y axis to get total displacement:

X=Acos30-15+5cos37=A root 3/2-11:

Y=asin30+7-5sin 37=a/2 +4

So, resultant vector=displacement =  √(X2 +Y2))  =   (a√3/2 -11)2  +(a/2+4)2.By solving the above we can get the displacement.

Mass of the ball ,a , is not indicated.

So, value could not be calculated.
