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).

A missile is shot straight up into the air. At the peak of its trajectory, it breaks up into three pieces of equal mass, all of which move horizontally away from the point of the explosion. One piece travels in a horizontal direction of 35° east of north with a speed of 31 m/s. The second piece travels in a horizontal direction of 11° south of west with a speed of 7 m/s. What is the velocity of the remaining...
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...
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...

The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.

1. An airplane leaves airport A and travels in a straight line in a direction 30 degrees East of North at a constant speed of 300km/hr for 40 minutes, then it abruptly changes its direction to 25 degrees South of East and now travels at a constant velocity of 200km/hr for 30 minutes, and finally it abruptly heads directly South and travels at a velocity of 300km/hr for 60 minutes before landing at airport B. (a) calculate the distance, D,...

. Let us examine a ball in the process of bouncing off of a floor. As we discussed briefly in class, if the ball has spin then this is a very complicated problem. So let us assume that the ball has no spin for the duration of the bounce. The ball hits the floor going vertically down. (a) Draw a motion diagram showing the motion of the center of mass of the ball during the bounce. We are only interested...

In a scene from a classic cartoon, a hungry coyote is chasing a roadrunner, as shown in the figure below. To aid in his quest, he has donned a pair of ACME brand rocket-propelled roller skates. The skates accelerate the coyote at 14.0 m/s n the horizontal direction. The roadrunner is moving at a constant speed toward a cliff. The coyote is initially at rest 30.0 m from the cliff at the instant the roadrunner moves past him. (In all...
