1. Shrek launches a projectile is fired from ground level with an initial speed of 50 m/s at an angle of 52o
toward the castle. The base of the castle is 200 m from where the projectile is fired.
a. Determine the time it takes for the projectile to reach the castle.
b. Calculate the height above the ground at which the projectile strikes the castle.
c. Determine the magnitude and direction of the projectile velocity when it reaches the castle.
d. Calculate the maximum height the projectile will reach.
30°
40 m/s
2. A rocket is fired from the edge of a cliff 50 m high with an initial speed of 40 m/s at an angle of 30o
below the horizon.
a. Determine the velocity of the projectile in the y-direction right before it hits the ground.
b. Determine how much time the projectile is airborne.
c. Determine the distance from the base of the cliff that the projectile lands.
d. Determine the magnitude and direction of the speed of the projectile when it strikes the ground.

3. A potato is projected from the top of a 20-m tall building with a "potato gun" at an initial speed of 40
m/s and angle 35° to the horizontal.
a. Determine the resultant speed of the potato when it strikes the ground.
b. Determine how much time the potato is in the air.
c. Calculate the maximum range of the projectile.
d. Sketch the velocity time graph for both the x and y direction.
4. A truck on a straight road starts from rest accelerating at 2.5 m/s2 until it reaches a speed of 25 m/s.
Then the truck travels for 20s at a constant speed, then brakes for 5s, stopping the truck.
a. Determine the total time the truck is in motion.
b. Determine the total displacement of the truck.
c. Determine the average speed for the trip.
