Problem #1: To find
out where the cannon ball will land, given the initial velocity ( v0) and the firing angle (θ0)
(The parameters whose values are known are highlight in red.
The main direction of solving a problem: try to derive equations
that use these parameters with known values.)
Change the values for v0 and θ0 in
the equations below, and then click the Calcuate button to calcuate
the vx0 and
vx0 = v0 × cos θ0
m/sec. × cos
(degree) = 6.928 m/sec.
vy0 = v0 × sin θ0
m/sec. × sin
(degree) = 4 m/sec.
