- 13. A net force of 345 N accelerates a boy on a sled at 3.2 m/s?. What is the combined mass of the sled and boy?19. As you sit in your chair and study your physics (presuming that you do), the force of gravity acts downward upon your body. The reaction force to the force of the Earth pulling you downward is a. the force of the chair pushing you upward b. the force of the floor pushing your chair upward c. the force of the Earth pushing you upward d. the force of air molecules pushing you upwards e. the force of your body pulling the Earth upwards f . nonsense! Gravity is a field force and there is no such reaction force. Justify your answer:8)Pulling up on a rope, you lift a 4.40-kg bucket of water from a well with an acceleration of 2.50 m/s2. What is the tension in the rope?
- 6. Complete the following statement: "When the Total Blue Force is NOT EQUAL TO the Total Red Force, the net force is (zero / not zero) and the forces are (balanced / unbalanced). The object (same / opposite) direction accelerates in the as the net force."For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 27 N acts on a certain object, the acceleration of the object is 9 m/s“. If the force is changed to 18 N, what will be the acceleration of the object? 2 olo3. A net force of 32 N acting upon a wooden block produces an acceleration of 4.0 m/s2 for the block. What is the mass of the block?
- 10. Imagine you are pushing a car: a. If you kept the force you exerted the same, but doubled the mass of the car, would the acceleration you achieve be twice as much or half as much or the same? b. If you pushed the original car twice as hard, would the acceleration you achieve be twice as much or half as much or the same as when you pushed it with your original force? 11. Predict where this balloon will go by drawing an arrow that represent the direction of its acceleration I4. Use the following five words (together with other words) in a single sentence that makes scientific sense: kinetic, static, normal, coefficient, accelerate.A- Calculate the weight of a person who has a mass of 100kg. ____kg m/s/s B- A grocery bag can with stand a force ( weight ) of 49N before it rips apart, how many kilograms of apples can it safely hold? ____kg.
