A man is in a room with a ceiling ht of 7m. If while standing 20m from a wall he launches a ball from 1.6 m above the floor with v = 15 m/s, what is the max height at which the ball can hit the wall? Please Provide Steps( a logical step through process)
You (mass = 75 kg) are riding in an elevator while standing on a scale. As the elevator begins to rise, you notice that the scale reading briefly increases to 785 N. What is the acceleration of the elevator during this time? Assuming it has three times the acceleration as it slows to rest at the top floor, what does the scale read as it slows?
You push your 55.0 kg refrigerator by a horizontal force of 113 N, but your refrigerator does not move. What is the force of friction between refrigerator and the floor? (Enter the magnitude in newtons.)
You push your 49.0 kg refrigerator by a horizontal force of 110 N, but your refrigerator does not move. What is the force of friction between refrigerator and the floor? (Enter the magnitude in newtons.)
3. You crouch from a standing position, lowering your center of mass 18 cm in the process Then you jump vertically. The average force exerted on you by the floor while you jump is three times your weight. What is your upward speed as you pass through your standing position in leaving the floor? Answer |2.7 m/s
To tighten a bolt, you push with a force of 90 N at the end of a wrench handle that is 0.5 m from the axis of the bolt. (a) What torque are you exerting? (b) If you move your hand inward to be only 0.10 m from the bolt, what force do you have to exert to achieve the same torque?
To move a large crate across a rough floor, you push on it with a force F at an angle of 21 ∘ below the horizontal A.)Find the force necessary to start the crate moving, given that the mass of the crate is 32 kg and the coefficient of static friction between the crate and the floor is 0.60.
The mass of a publix shopping
cart is 30.00kg. While shopping, if you push a cart with a force of
35.0 N directed at an angle of 25.0° downward from the horizontal.
as it moves a horizontal distance of 50 m, what is the work done by
you on the cart?

To move a large crate across a rough floor, you push on it with
a force F at an angle of 21 ? below the horizontal, as
shown in the figure (Figure 1) .
Find the force necessary to start the crate
moving, given that the mass of the crate is 32 kg and the
coefficient of static friction between the crate and the floor is
0.57.
To move a large crate across a rough floor, you push on it with a force F at an angle of 21 ∘ below the horizontal, as shown in the figure.(Figure 1) Part A Find the acceleration of the crate if the applied force is 380 N , the mass of the crate is 32 kgand the coefficient of kinetic friction is 0.30. Express your answer using two significant figures.
