Consider the following question - a cannon is shot with an initial velocity of 3\hat i+5\hat j m/s it's initial position in meters is at (0,1). The cannonball takes 4 seconds to hit the ground. how far did the cannon move horizontally when it hits the ground? Assume no air resistance
Using the GUESS method:
Givens - ________________________________________ = 3 m/s, ________________________________________ =5 m/s, ___________________________________ = 0m, __________________________________________ =1 m, _________ =4 s, ________________________________ = -10 m/s^2 (assumed, not given), ____________________________________ =0 m/s^2
Unknowns ______________________________________________________________
Other Answer Choices:
position in the x direction when the ball hits the ground
Initial velocity in the x direction
initial position on the x axis
acceleration in the x direction
time
initial velocity in the y direction
Acceleration due to gravity
initial position in the y direction.

Consider the following question - a cannon is shot with an initial velocity of 2\hat i+6\hat j m/s? it's initial position in meters is at (0,1). When does the cannonball reach its highest point Assume no air resistance
Using the GUESS method:
Givens - ________________________________________ = 2 m/s, ________________________________________ =6 m/s, ___________________________________ = 0, __________________________________________ =1 m, ________________________________ = -10 m/s m/s^2 (assumed, not given), ____________________________________ =0
Unknowns _________
