Chapter 4, Problem 49PCE
Predict/Calculate Volcanoes on lo Astronomers have discovered several volcanoes on lo, a moon of Jupiter. One of them, named Loki, ejects lava to a maximum height of 2.00 × 105 m. (a) What is the initial speed of the lava? (The acceleration of gravity on lo is 1 80 m/s2.) (b) If this volcano were on Earth, would the maximum height of the ejected lava be greater than, less than, or the same as on lo? Explain.

7. In the scenario below, a Determine how long was the magma in the air before hitting the ground. (Round to the nearest hundredth) b). Determine the vertical velocity of the magma when it hits the ground?(Round to the nearest tenth) c What was the height (m) (vertical distance) from which the magma was launched. (Round to the nearest whole meter)
A volcano erupts and launches a chunk of hot magma horizontally with a speed of 330 m/s. The magma travels a horizontal distance of 1500 m/s
before it hits the ground. We can ignore air resistance.
In 2004 two Martian probes successfully landed on the Red Planet. The final phase of the landing involved bouncing the probes until they came to rest (they were surrounded by protective inflated “balloons”). During one of the bounces, the telemetry (electronic data sent back to Earth) indicated that the probe too off at 25.0 m/s at an angle of 20 degrees and landed 110 m away (and then bounced again). Assuming the landing region was level, determine the acceleration due to gravity near the Martian surface.
Differential equations
A sphere weighing 2 kg is dropped from a height of 1000 meters without initial speed. While falling you find an air resistance numerically equal to v/8 (in Newtons) where v is the speed of the sphere (in m/s).Find: a. The speed lımite of the sphere .b. The time required for the sphere to touch the ground.

- Construct Your Own Problem Consider a ball tossed over a fence. Construct a problem in which you calculate the ball's needed initial velocity to just clear the fence. Among the things to determine are; the height of the fence, the distance to the fence from the point of release of the ball, and the height at which the ball is released. You should also consider whether it is possible to choose the initial speed for the ball and just calculate the angle at which it is thrown. Also examine the possibility of multiple solutions given the distances and heights you have chosen.arrow_forwardAn outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in Figure P4.46, but that the balls speed after the bounce is one-half of what it was before the bounce. (a) Assume the ball is always thrown with the same initial speed and ignore air resistance. At what angle should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 45.0 with no bounce (green path)? (b) Determine the ratio of the time interval for the one-bounce throw to the flight time for the no-bounce throw. Figure P4.46arrow_forwardConstruct Your Own Problem Consider an airplane headed for a runway in a cross wind. Construct a problem in which you calculate the angle the airplane must fly relative to the air mass in order to have a velocity parallel to the runway. Among the things to consider are the direction of the runway, the wind speed and direction (its velocity) and the speed of the plane relative to the air mass. Also calculate the speed of the airplane relative to the ground. Discuss any last minute maneuvers the pilot might have to perform in order for the plane to land with its wheels pointing straight down the runway.arrow_forward

Find the speed of the raft.arrow_forward7. Sally is driving at a constant speed of 25 m/s on a straight horizontal road. She sees an obstacle on the road ahead and applies the brakes!

- In the 1970 National Basketball Association championship, Jerry West made a 60 ft shot from beyond half court to lead the Los Angeles Lakers to an improbable tie at the buzzer with the New York Knicks. Suppose West threw the ball at an angle of 40.0∘ above the horizontal. The basket is 10 ft from the court floor. Neglecting air resistance, estimate the initial speed of the ball. (The Knicks won the game in overtime.)arrow_forward. In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incrediblespeeds. In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” Hedoes this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Isthe physics of this scene “Good,” “Bad,” or “Ugly”? Explain.arrow_forwardTwo youngsters dive off an overhang intoa lake. Diver 1 drops straight down, and diver 2 runs off the cliffwith an initial horizontal speed v0.

Both divers are in free fall, and hence they will have the samesplashdown speed.II. The divers have the same vertical speed at splashdown, butdiver 2 has the greater horizontal speed.III. The diver who drops straight down gains more speed than theone who moves horizontally.arrow_forward
