- . 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?A single-celled animal called a paramecium propels itself quite rapidly through water using its hair-like cilia. A certain paramecium experiences a drag force of ?drag=−??2 in water, where the drag coefficient ? is approximately 0.330 kg/m . If the paramecium's speed ? is 0.000137 m/s , what is the magnitude of the propulsion force that the creature must generate to move at this constant speed?A bus is accelerating at a rate of 10 m/s2. What is the new acceleration of the car if the force is doubled and the mass is halved? A 565 kg minecart is travelling at 78 km/hr. What is the average force required to stop the minecart in 23 s?
- You are moving boxes into a new apartment. One of the boxes is very heavy, with a mass of 40kg, so you need to push it across the carpet instead of carrying it. If the box is accelerating at 3.2 m/s2 to the right because of your push of 121 N, what is the force of the friction on the box? What is the normal force on the box? What forces are acting on the box?Once you reach the 21st floor you decide that your urge to understand physics is too great so you decide to ride the elevator back to the ground floor to analyze what happens. The elevator accelerates downward at 2 m/s2. What is the Gravitational Force? Since the elevator is accelerating downward does the Normal Force have to be greater than, equal to or less than the Force of Gravity? Are the forces balanced or unbalanced? Draw a free body diagram of the forces acting on you. Be sure to draw the size of your arrows appropriately. What is the Net Force, using Newton’s 2nd Law, while the elevator is accelerating downward? What is the Normal Force? What does the scale read as the elevator is accelerating downward1. Which statement about Issac Newton is not true? A. Made huge advances in math, science, and other area B. His discoveries came naturally in "flashes of brilliance" due to his genius C. He came from very humble beginnings D. He thought long and hard to solve problems 2. An object falling at a steady rate as the force of gravity is equal to air resistance, is not in a state of a. Dynamic equilibrium b. Mechanical equilibrium c. non-free fall d. Free-fall 3. An object falling under only the influence of gravity is in a. Free fall b. Non-free fall c. Mechanical equilibrium d.

- football quarterback throws a 0.107 kg football for a long pass. While in the motion of throwing, the quarterback moves the ball 2.697 m , starting from rest, and completes the motion in 0.892 s . Assuming the acceleration is constant, what force does the quarterback apply to the ball during the pass? Fthrow = _________________ N *Round to the nearest thousandth if necessary.A force of 61 N causes a rock to accelerate at a rate of 4 m/s2. What is the mass? I'm sorry our physics teacher does not teach us anything!2. How much force is needed to stop a 10 kg object moving at 4 m/s in just 10 s? Explain your answer.
- hi , pls help me understand how this is solve. thank you so much a) a dictionary is pulled to the right at constant velocity by a 10N force acting 30 degrees upward above the horizontal. the coefficient of kinetic friction between the book and the horizontal surface is 0.5. what is the weight of the book? also, pls draw a diagram with proper labels for added information so I can understand it fully. thanks againWhat is the answer and draw the FBD. In an airplane crash a woman is holding an 8.18 kg, 18 pound, baby. In the crash the woman experiences a horizontal de-acceleration of 88.2 m/s2. How many g's is this de-acceleration? How much force must the woman exert to hold the baby in place?A 44 kg box is moving at a constant acceleration of 1.8 m/s2. What is the force acting on the box?
