An object is thrown horizontally and after 3 seconds the speed vector forms the angle pi/4 radians with the horizontal direction. FInd the speed after 4 seconds.
Homework Equations
v=gt
The Attempt at a Solution
As it forms the angle pi/4 radians, vx=vy, so
v0=gt=3*10=30
vy when t=4 is 40m
v=sqrt(vx^2+vy^2)=50m Am I right
