. The Kingda Ka roller coaster in New Jersey is the world’s tallest ride of its kind. As the passenger cars are launched from rest at the start, they are accelerated uniformly to a speed of 57 m/s (128 mph) in just 3.5 s. (a) What is the acceleration experienced by passengers on this ride in m/s2? In g’s? (b) If a certain passenger has a mass of 65 kg, what is the force in newtons that acts on him during the launch phase of this ride? What is the force in pounds?
1. A 17.43kg object speeds up from 14.86m/s to 48.05m/s over a distance of 100.90m. What is the acceleration of the object? If the frictional force is 17.99N, what is the net acceleration acting on the object? 2. Goku's birthplace (in Dragon Ball Z universe) is planet Vegeta which has a really high surface gravity, that is why he can jump really high on Earth because the gravity on the said planet is really wimpy and cannot hold him down. Up to what height can Goku jump on planet Vegeta if he can jump on earth up to a height of 3098.88m and the planet Vegeta has 448.90% stronger gravity? Assume that Goku launched himself on the same initial velocity for both planets. What is his weight on planet Vegeta if his mass is 98.16kg? 3. A coin dropped from a certain building with a height of 4554.10m. If we hypothetically assume that the 314.87 u mol-coin is made of pure nickel and that nickel has a molar mass of 59g/mol, what is the force of the coin as it hits the asphalt?
1.supposed that the body with 2 kg has an initial velocity of 10m/s and is then pulled 4 meters by a force of magnitude 25N in the direction of the initial velocity, what is its final velocity?
1. The brakes of a 1000kg car exert 3000N How long will it take the car to come to a stop from a velocity of 30 m/s? How far will the car travel during this time? 2. Draw the FBD of the following. An egg is free-falling from a nest in a tree. Neglect air resistance. A rightward force is applied to a book in order to move it across a desk with a rightward acceleration. Consider frictional forces. Neglect air resistance.
1. A newborn baby’s brain grows rapidly.In fact, it has been found to increase in mass by about 1.6 mgper minute. (a) How much does the brain’s weight increase in one day? (b) How long does it take for the brain’s weight to increase by 0.15 N? Graph and Explain.
7. An object has an initial velocity of 5 m/s East then speeds up to 25 m/s East in 4 seconds. What is the acceleration of the mass? Here are the choices: 5 m/s2 -5 m/s2 6 m/s2 -6 m/s2
. 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.
A 1500 kg car traveling at 15 m/s suddenly runs out of gas while approaching the valley shown in the figure(Figure 1). The alert driver immediately puts the car in neutral so that it will roll. What will be the car’s speed as it coasts into the gas station on the other side of the valley?
When a 0.058 kg tennis ball is served, it accelerates from rest to a speed of 45.0 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 0.440 m. What is the magnitude of the net force acting on the ball? What is the average velocity of the ball? Over what time period was the ball struck? What is the acceleration of the ball? What is the net force on the ball? If the ball had been heavier, but experienced the same change in velocity, would the applied force have to be greater or lesser than before?
