A cricket player is capable of throwing a ball at velocity v. Neglecting air resistance, what angle from the horizontal should they throw at to achieve maximum distance before contact with the ground? How far is that distance?

Assume angle of throw theta. Resolving vertical and horizontal components: Vvert=v.sin(theta) and Vhoriz=v.cos(theta).From 'suvat' equations, time to vertical stationary t=v/a. This must be doubled to find t...

Find the GS to the following 2nd ODE: d^2y/dx^2 + 3(dy/dx) + 2 = 0

Set up the auxiliary equation by letting (dy/dx) = m So we have: m 2 + 3m + 2 = 0 Solve for m and we get: (m+1)(m+2) = 0Therefore, m 1 =-1 and m 2 =-2 Now we see we have 2 different real numbers as the solut...
