Set the cannon height to 14 m and the initial speed to 20 m/s. Show how to calculate the location of the target. Verify your prediction using the simulation.

Explanation:

The location of the target can be determined by calculating the horizontal distance according to the projectile formula

R = U*√2H/g

U is the initial speed = 20m/s

H is the maximum height = 14m

g is the acceleration due to gravity = 9.81m/s²

Substitute

R = 20*√2(14)/9.81

R = 20√28/9.81

R = 20√2.85

R = 20(1.689)

R = 33.79m

Hence the location of the target is at 33.79m

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
