Let us assume that a cannonball is shot straight west from Bergen at an average horizontal speed of 200 ms−1. After 30s the cannonball hits the water. Neglecting friction, how far from the latitude of Bergen does the cannonball hit the water? (suggestion: Assume constant u, and calculate the acceleration and the distance travelled in the north-south direction during the flight).

Suppose at one point along the Nile River a ferryboat must travel straight across a 1.22-mile stretch from west to east
Suppose at one point along the Nile River a ferryboat must travel straight across a 1.22-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.31 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 27.1 mph in still water. If the captain points the boat directly at the target location on the east bank of the river, how far downstream will...

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop?

Answer: 10.12 A key is dropped from a bridge that is 40.0 m bove the water. At the moment the key is released a model boat is 10.5 m away from the bridge and moving towards the bridge with constant velocity. If the key falls directly into the model boat, calculate the Velocity of the boat. Answer: 11. [2pt] Arie is aimed honuntaily a target located 345 m away.

HW#5 Functions and Arrays
For HW#5 we will return to the state method of solving the
ballistic projectile problem with added twists. The goal will be to
hit a target 1000 meters east of your cannon but the wind is
blowing from the south. Your initial muzzle velocity is fixed at
110 meters per second, but you can control the elevation and
azimuth angles of your aim. Elevation angle is measured up or down.
Azimuth angle is measured right or...
