- A 150kg fish swimming at 8.0m/s swallows a 15kg fish swimming towards it at 4.0m/s. What is the speed of the larger fish immediately after eating the little fish?A student releases a marble from the top of a ramp. The marble increases speed steadily and travels 170cm in 4.80s. What was the marble's final speed (in given units)?6. A crazy, young boy on a sled is able to get up to an incredible speed of 22.5 m/s (yes, he is wearing a helmet!) along a frictionless horizontal surface while he approaches an icy hill with a vertical height of 11 m, as shown. He makes it to the top, and then flies off horizontally from the ledge of the hill. How far from the base of the hill does the boy land? 225 mis Figure 1
- A ball is thrown into a wall at a speed of 20 m/s and bounces off going 10 m/s in the opposite direction 0.2s after hitting the wall. What is the acceleration of the ball?A small rocket launched straight up. When at a height of 5.0km and velocity of 200.0 m/s, it is releases its booster and enters free fall. Neglecting air friction, 1. what is the velocity of the rocket at a height of 6.0km on its way up? A. 142 m/s B. 200 m/s C. 244 m/s D. 397 m/s 2. What is the maximum height, above the ground, the rocket attains? A. 2020m B. 5000m C. 7040m 3.

Siblings Alice and Bob saved their money all summer to buy a water balloon launcher, and they are eager to take it for a test run. Younger brother Bob thinks he's a pretty fast runner with a top speed of 5 m/s. Не poses the following challenge to his sister: "I'll stand 20 m from you and I'll start running away as soon as you launch a water balloon. See if you can hit me!" Unfortunately for Bob, Alice is a physics 8A ace and knows exactly what needs to be done to soak her brother. (a) Set the origin of your coordinate system at Alice's position with Bob starting along the positive x-axis (and running along the x-axis). Assuming Bob runs at a constant velocity, what is Bob's trajectory rB(t)? (b) Suppose the water balloon launcher is limited to only firing at an angle of T/4. In terms of the unknown initial launch speed v, what is the trajectory of the water balloon rwB(t)? (c) What speed v should Alice launch with to ensure a direct hit? (d) How long does the balloon take…

- Abby throws a ball straight up and times it. She sees that the ball goes by the top of a flagpole after 0.400 s and reaches the level of the top of the pole after a total elapsed time of 4.00 s. What was the speed of the ball at launch?To settle an argument Dr Goulding and his Mrs (his wife) decide to have a 40.0 m lang snowshoe race, with the prize being a very nice locally made face mask. At the start line they shake hands and when their cat helper Charlie fires the start gun they begin running on thier snowshoes. Dr Gaulding reaches his maximum speed of speed of 2.68 m/s in a time of 10.0 s while The Mrs accelerates to her maximum speed of 3.00 m/s at a rate of a,-0.20 m/s2 How far are they apart when the runners have both reached their maximum running speeds? Your Answer: Answer unitsA 2 kg ball is thrown off a 73 m high cliff with a speed of 4 m/s. How fast (in m/s) is the ball going when it hits the ground? Use g = 9.8 m/s2.
