1. If a ball is thrown with a velocity of 25 m/s at an angle of 37° north of west, what are the components of its velocity?

6. You launch a projectile with an initial speed of 48.8 m/s from the top of a building 66.2 m above the ground, at an angle of 45.1 degrees above the horizontal. How far from the base of the building does the projectile land on the ground?  242.8 m  269.8 m  370.9 m  296.7 m

3. Consider a ball undergoing a 2D projectile motion, whose position (unit: m) as a function of time (unit: s) is 3(t) = tî + (V3t – 5t²)ĵ, where t stands for time. (a) Find the initial launch angle of the projection. (b) Find the speed of the ball when it lands on the ground.

To start an avalanche on a mountain, an artillery shell is fired from 1250 m from the base of the mountain at 300 m/s, 55.0°. What are its coordinates 9.0 seconds later?     Where does it hit on the mountain?   If you are unable to answer, draw a diagram showing why.

8. A projectile is fired from the ground, reaches a maximum height of 57.1 m and lands a distance of 52.9 m away from the launch point. What was the projectiles launch velocity?  55.0 m/s, 30.8 degrees above horizontal  34.4 m/s, 77.0 degrees above horizontal  33.5 m/s, 38.5 degrees above horizontal  7.8 m/s, 61.6 degrees above horizontal

4. A hockey player makes a shot 4m away from goal at a horizontal velocity of 15 m/s. How long does the goalie have to react to the shot?

Question 3

2. Your friend is stranded on the other side of a canyon, as shown below. He's getting hungry and so you decided to throw him a banana. You throw the banana with an initial velocity of 20 m/s at and angle 37° above the horizontal. The canyon is 8 m wide and your friend is on a plateau that is 5 m above your elevation. (a) Find the horizontal (x) and vertical (y) components of the banana's initial velocity. (b) Determine whether or not the banana will reach your friend on his side of the canyon (i.e., will he get to eat the banana?).

10. You launch a projectile horizontally from a building 39.0 m above the ground at another building 25.8 m away from the first building. The projectile strikes the second building 6.4 m above the ground. What was the projectiles launch speed?  22.59 m/s  28.24 m/s  10.01 m/s  9.15 m/s

4. The Incredible Hulk, chased by the army, leaps with speed 16_m/s at a 57° angle above the horizontal from the top of a building. If he lands 59 m from the base of the building, then find the height of the building.
