A block is on a frictionless table on earth. The block accelerates at 3.0m/s2 when a 20 N horizontal force is applied to it. The block and table are set up on the moon. The acceleration due to gravity at the surface of the moon is 1.62cm/s2. The weight of the block on the moon is closest to Can someone given the answer and an explanation of how you got it?
A 6 kg block sits at rest on a frictionless horizontal table. A 12 N horizontal force is suddenly applied to the block and maintained as the block begins moving. What is the acceleration of the block after the force is applied? What is the speed of the block after it has moved a distance of 0.5 m?
1 a). If I weigh 215lbs on earth, how much would I weigh (in pounds) on the moon where the acceleration due to gravity is 1.625 m/s2. b). A horizontal force of 86.7 N is applied to a 50.5 kg crate on a rough, level surface. If the crate accelerates at 1.03 m/s2, what is the coefficient of kinetic friction between the crate and then surface?
A horizontal force of 99 N pushes a 11 kg block up a frictionless incline that makes an angle of 41° with the horizontal. (a) What is the normal force that the incline exerts on the block? =N (b) What is the acceleration of the block? (Hint: assume up the block as the positive direction.) =m/s2
A block whose weight is 42.6 N rests on a horizontal table. A horizontal force of 34.1 N is applied to the block. The coefficients of static and kinetic friction are 0.640 and 0.390, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s2 as the acceleration.
A 4.7 kg block is being pushed across a frictionless horizontal surface by a horizontal force. The block accelerates at 3.8 m/s2. What is the magnitude of the normal force the surface exerts on the block? Express your answer in newtons and round to one decimal place.
A 3.9 kg block is being pushed across a frictionless horizontal surface by a horizontal force. The block accelerates at 5.6 m/s2. What is the magnitude of the normal force the surface exerts on the block? Express your answer in newtons and round to one decimal place.
3. Two blocks of given mass are in contact on a frictionless horizontal table. A horizontal force is applied to one block, F. Find the acceleration of both blocks and the force between them.
Problem 3 A 6-kg block is moving on a horizontal frictionless floor with a speed of 4 m/s when a constant horizontal force F is applied to the block. The speed of the block increases to 10 m/s within a distance of 5 m. Find (a) initial and final kinetic energy, and (b) the applied force F Problem 4 A0.50 kg block sliding on a horizontal frictionless surface with a speed of 2.5 m/s strikes a light spring that has...
A horizontal force of 40 N acting on a block on a frictionless level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration of the combination of blocks if the same force continues to act? (Assume that the second block does not slide on the first block.)
