Problem 1 ( . You are on one bank of a river at height h want to jump across the river to the opposite bank, which is at the same height as the river horizontal distance d = 1.5 m away. = 2m above the river. %3D d (a) If you leave the bank of the river at an angle 0 = 30°, what initial speed do you need to just barely make it to the other side? (b) If you jump at this angle and with the speed you found in (a), what is your speed just before you land on the other side of the river? (c) Suppose that when you land on the other side of the fiver, an average force of 14 000 N brings you to rest. Assuming all of this force is exerted on your tibia, what is the percent change in the length of your tibia as you are landing? Assume the tibia has a cross-sectional area of 3 cm? and a Young's modulus of 1.4 x 1010 Pa.
A rescue plane flying horizontally at 252 km/hr in still air spots a survivor in the ocean 180 m directly belowwhen it releases an emergency kit. Air resistance slows the descent such that the kit falls with a constant verticalacceleration of 6.00 m/s2 downward. Due to the shape of the kit, air resistance in the horizontal direction isnegligible. How far from the survivor does the kit land in the water?
A skier leaves the end of a horizontal ski jump at 21.0 m/s and falls through a vertical distance of 3.30 m before landing. (a) Neglecting air resistance, how long does it take the skier to reach the ground? s (b) How far horizontally does the skier travel in the air before landing? m
A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away. What are the givens in the y-direction? v0y = 0 m/s; ay = -9.8 m/s2; Δy = 18 m v0y = 0 m/s; ay = -9.8 m/s2 v0y = 45 m/s; ay = 0 m/s2; Δy = 18 m v0y = 45 m/s; ay = -9.8 m/s2; Δy = 18 m
4. A daring swimmer drives off a cliff with a running horizontal leap, as shown in the figure. What must her minimum speed be as she leaves the top of the cliff so that she will miss the ledge at the bottom, which is 1.75 m wide and 9.00 m below the top of the cliff?
You are really angry at your family, and in your frustration you decide you are going tothrow the pizza you bought for dinner onto the roof of your house. You are 6 metersfrom the house and the roof of the house is 3 meters above the ground. Assuming youtoss the pizza from ground level with an initial speed of 10 m/s at an angle of 60° (abovethe horizontal), how far onto the roof does the pizza land? Assume the roof is flat.
