An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 5.2 m/s. A child on a bridge, 82 m above the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone? m
A diver runs off a platform with an initial horizontal velocity of 1.16 m/s in the positive x-direction. The platform is at a vertical height of 8.90 m above the water. How much time is the diver in the air before he strikes the water? O 1.77 s O 1.83 s O 3.21 s O 2.49 s O 1.35 s O 2.99 s
You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
Chinook salmon can cover more distance in less time by periodically making jumps out of the water. Suppose a salmon swimming in still water jumps out of the water with velocity 6.03 m/s at 40.6° above the horizontal, re-enters the water a distance L upstream, and then swims the same distance L underwater in a straight, horizontal line with velocity 2.92 m/s before jumping out again. Where L=3.67 m; t1= 0.801 sec this is a time when fish are over the water; t2= 1.256 sec; Ttotal =2.057 sec; the average horizontal velocity is 3.57 m/s. Consider the interval of time necessary to travel 2L. How is this reduced by the combination of jumping and swimming compared with just swimming at the constant speed of 2.92 m/s? Express the reduction as a percentage.
A lacrosse player is practicing against a wall. The ball leaves his stick 2.3 meters above the ground at a 33.5 degree angle from the horizontal with a speed of 9.3 m/s. The ball then hits the wall, 3.7 meters away. How high above the ground does the ball make contact with the wall?
A rocket is fired at a speed of 83.0 m/s from ground level, at an angle of 45.0° above the horizontal. The rocket is fired toward an 12.5-m high wall, which is located 21.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall?

Your nephew got a Nerf Bazooka gun for Christmas, so you take it outside to play with it (just like my uncles did when I was little). The bazooka is on your shoulder, 1.5 m above the ground. You aim the gun 25° above the horizontal and the big, foam projectile leaves the gun with an initial velocity of 36 m You accidentally aim the bazooka at a tree that is a horizontal distance of 27 m away. How long does it take for the projectile to hit the tree? t = How high (above the ground) in the tree does the projectile get stuck? hfinal = m Imagine you were more clever and aimed into an empty field with no obstructions. You can control how fast the projectile leaves the gun by pumping more times or fewer times (more pumps = faster projectile). What are TWO ways you could increase the amount of time that the projectile is in the air?
A skateboarder decides to try to jump from the top of a set of stairs and land at the bottom. She leaves the top of the stairs with a horizontal velocity of 15.0 m/s. If the top of the stairs is 2.0 m high, what will her horizontal displacement be?
Your little sister is running to the park in your neighborhood at a speed of 3.90 m/s when you suddenly realize she left her favorite playground ball behind. You throw her ball horizontally out the window of your apartment which is at a height of 45.0 m above the street and directly above the sidewalk. You throw the ball 8.00 seconds after she has passed below your window and she catches the ball! a) Ignoring air resistance, what is the initial speed that you must throw her ball so she can catch it just before it reaches the ground? b) How far down the sidewalk from the window is your sister when she catches her ball?
To celebrate her good performance on a physics test, Alice decides to break out a bottle of champagne. In order to avoid property damage, she takes the bottle outside to uncork it. The cork pops off the champagne bottle with a velocity of 12.0 m/s at an angle of 15° relative to the vertical. When the cork is released, Alice is holding the bottle such that the cork is 1.80 m above the ground. How far does Alice have to walk to retrieve the cork?
A golfer is trying to hit their ball over a 20 m tree. The ball leaves their club at an angle of 28° above the horizon. What is the minimum speed the golf ball would need to have after being hit by the club to make it over the tree?
On a beautiful spring day, Juan is playing a round of golf. He hits the golfball with an initial velocity of 37 m/s at an angle of 27.4°. If it hits the ground 5.8s later, how far does it travel? Ignore air resistance. Answer: m
