The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. In a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. The toothpick mass was 0.15 g, its speed before entering the branch was 212 m/s, and its penetration depth was 17 mm. If its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick? Number i Units +

For mammals, resting heart rate scales as mass to the -1/4th power; that is, R is proportional to m^-1/4. The heart rate of a 5000 kg elephant is 30 bpm (beats per minute). What do you predict for the heart rate of a 5.0 kg monkey?
For a ballistic study, a 1.9-gram mass bullet is fired into softwood. The bullet strikes the wood surface with a velocity of 380 m/s and penetrates 0.15 m. Find the time required to stop the bullet in seconds. Express your answer in FIVE (5) significant figures.
The small archerfish (length 20 to 25 cm) lives in brackish waters of Southeast Asia from India to the Philippines. This aptly named creature captures its prey by shooting a stream of water drops at an insect, either flying or at rest. The bug falls into the water and the fish gobbles it up. The archerfish has high accuracy at distances of 1.2 m to 1.5 m, and it sometimes makes hits at distances up to 3.5 m. A groove in the roof of its mouth, along with a curled tongue, forms a tube that enables the fish to impart high velocity to the water in its mouth when it suddenly closes its gill flaps. Suppose the archerfish shoots at a target that is 2.00 m away, measured along a line at an angle of 30.0 above the horizontal. With what velocity must the water stream be launched if it is not to drop more than 3.00 cm vertically on its path to the target?
A farmer selected a variety of a fast-growing vegetable which matures based on the differential equation dW/dt = 0.1W + 10, where W is the weight (in kilograms) of the available vegetables at time t (in months). An initial number of the vegetable of weight 46 kilograms were planted. How much can be harvested after 4 months? Assume that no vegetable dies. Do not round off intermediate steps. Round off the final answer to two decimal places.

As of August 27, 2020, the Philippines, through the Department of Finance has already borrowed $ 8.83 billion to fight against the health and socioeconomic crises inflicted by the COVD19 pandemic. (a) If payments were made at the rate of $1000 per second, how many many years would it take to pay off the debt, assuming no interest was charged? A one-dollar bill is about 15.5 cm long. If $8.83 billion one-dollar were laid end to end around the Earth's equator, how many times would they encircle the planet? Take the radium of the Earth at the equator to be 6378 km.

A rod of length 24.00 cm has linear density (mass per length) given by λ - = 50.0 + 24.5x where x is the distance from one end, and is measured in grams/meter. (a) What is its mass? X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. g (b) How far from the x = 0 end is its center of mass? m Need Help? Read It
The maximum running speed (S) in km/hr and the corresponding body mass (m) in kg were determined for 55 different species of mammals. An empirical relation was determined to be: S[km/hr] = 5.7 (m[kg])2 . Note: The notation in this equation means, “inserting the mass (m) in units of ‘kg’, automatically calculates the maximum running speed (S) in units of ‘km/hr’. ” (a) What are the implied units for the “5.7” factor? Hint: recall that relations between physical quantities must be dimensionally consistent, and the chosen units must in turn be consistent with the dimensionality. (b) Re-write the equation so that it gives the maximum speed in units of “m/s” for a given body mass in “g”. Show all relevant details. If done correctly, you will need to use at least one unit conversion factor.
A study finds that the metabolic rate of mammals is proportional to m3/4, where m is the total body mass. By what factor does the metabolic rate of a 70.0-kg human exceed that of a 6.50-kg cat?
