1.A 2.05-mm-tall basketball player takes a shot when he is 6.02 mmfrom the basket (at the three-point line). If the launch angle is 23 ∘∘ and the ball was launched at the level of the player’s head, what must be the release speed of the ball for the player to make the shot? The basket is 3.05 mm above the floor. v= 2.This time, William Tell is shooting at an apple that hangs on a tree (see the figure (Figure 1)). The apple is a horizontal distance of 20.0 mm away and at a height of 4.00 mm above the ground. If the arrow is released from a height of 1.00 mm above the ground and hits the apple 0.590 ss later, what is the arrow’s initial speed? 3.Awheeled car with a spring-loaded cannon fires a metal ball vertically If the vertical initial speed of the ball is 2.0 m/sm/s as the cannon moves horizontally at a speed of 0.65 m/sm/s , how far from the launch point does the ball fall back into the cannon? What would happen if the cannon were accelerating?
A basketball leaves a player's hands at a height of 2.15 m above the floor. The basket is 3.05 m above the floor. The player likes to shoot the ball at a 35.0 ∘ angle. If the shot is made from a horizontal distance of 11.00 m and must be accurate to ±0.27 m (horizontally), what is the range of initial speeds allowed to make the basket? Enter your answers numerically separated by a comma. vmin,vmax? .......... m/s
10. A horizontally launched projectile lands 79.29m below the launch point and a horizontal distance of 127.04m from the launch point. How long did it take to hit the ground? 6.348s 2.366s 3.982s 5.405s None of these is correct.
6 A projectile is shot at ground level at an angle of 36° with the horizontal. It has an initial velocity of 109 m/s. Determine its velocity (m/s) 4 seconds after firing. ROUND OFF TO TWO DECIMAL PLACES.
Serving at a speed of 170 km/h, a tennis player hits the ball at a height of 2.5 m and an angle below the horizontal. The service line is 11.9 m from the net, which is 0.91 m high. What is the angle such that the ball just crosses the net? Will the ball land in the service box, whose out line is 6.40 m from the net?
Antlion larvae lie in wait for prey at the bottom of a conical pit about 5.0 cm deep and 3.8 cm in radius. When a small insect ventures into the pit, it slides to the bottom and is seized by the antlion. If the prey attempts to escape, the antlion rapidly launches grains of sand at the prey, either knocking it down or causing a small avalanche that returns the prey to the bottom of the pit. Suppose an antlion launches grains of sand at an angle of 72 above the horizon. Find the launch speed v0 required to hit a target at the top of the pit, 5.0 cm above and 3.8 cm to the right of the antlion.
A father demonstrates projectile motion to his children by placing a pea on his forks handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 8.25 m/s at an angle of 75.0 above the table. With what speed does the pea strike the ceiling 2.00 in above the table?
A golfer tees off from a location precisely at i = 35.0 north latitude. He hits the ball due south, with range 285 m. The balls initial velocity is at 48.0 above the horizontal. Suppose air resistance is negligible for the golf ball. (a) For how long is the ball in flight? The cup is due south of the golfers location, and the golfer would have a hole-in-one if the Earth were not rotating. The Earths rotation makes the tee move in a circle of radius RE cos i = (6.37 106 m) cos 35.0 as shown in Figure P6.47. The tee completes one revolution each day. (b) Find the eastward speed of the tee relative to the stars. The hole is also moving cast, but it is 285 m farther south and thus at a slightly lower latitude f. Because the hole moves in a slightly larger circle, its speed must he greater than that of the tee. (c) By how much does the holes speed exceed that of the tee? During the time interval the ball is in flight, it moves upward and downward as well as southward with the projectile motion you studied in Chapter 4, but it also moves eastward with the speed you found in part (b). The hole moves to the east at a faster speed, however, pulling ahead of the ball with the relative speed you found in part (c). (d) How far to the west of the hole does the ball land? Figure P6.47
Determine which of the following moving objects obey the equations of projectile motion developed in this topic. (a) A ball is thrown in an arbitrary direction. (b) A jet airplane crosses the sky with its engines thrusting the plane forward. (c) A rocket leaves the launch pad. (d) A rocket moves through the sky after its engines have failed. (e) A stone is thrown under water.
The eye of a hurricane passes over Grand Bahama Island in a direction 60.0 north of west with a speed of 41.0 km/h. Three hours later the course of the hurricane suddenly shifts due north, and its speed slows to 25.0 km/h. How far from Grand Bahama is the hurricane 4.50 h after it passes over the island?
An owl is carrying a mouse to the chicks in its nest. Its position at that time is 4.00 m west and 12.0 m above the center of the 30.0 cm diameter nest. The owl is flying east at 3.50 m/s at an angle 30.0° below the horizontal when it accidentally drops the mouse. Is the owl lucky enough to have the mouse hit the nest? To answer this question, calculate the horizontal position of the mouse when it has fallen 12.0 m.
The free throw line in basketball is 4.57 m (15 ft) from the basket, which is 3.05 m (10 ft) above the floor. A player standing on the free throw line throws the ball with an initial speed of 7.15 m/s, releasing it at a height of 2.44 m (8 ft) above the floor. At what angle above the horizontal must the ball be thrown to exactly hit the basket? Note that most players will use a large initial angle rather than a flat shot because it allows for a larger margin of error. Explicitly show how you follow the steps involved in solving projectile motion problems.
