- A box is given a push across a horizontal surface. The box has a mass m, the push gives it an initial speed of 2.40 m/s, and the coefficient of kinetic friction between the box and the surface is 0.140. (a) Use energy considerations to find the distance (in m) the box moves before it stops. m (b) What If? Determine the stopping distance (in m) for the box if its initial speed is doubled to 4.80 m/s. mA pretty box from taylor swift batumbakal with a mass of 20.0 Kg is moving at a speed of u = 8 m/s. The smooth platform on the top has h = 50 cm from the ground. On the other hand, the rough platform at the bottom and the box has a coefficient of kinetic friction = 0.325. Also, in the bottom platform, the pretty box was able to move by R = 11.0 m before the spring, whose a spring constant k = 390 N/m, is compressed and the box stopping 1. When the pretty box reaches the bottom platform, what is its speed? 2. When it touches the spring, what is its speed? 3. How much has the spring been compressed, when the box stopped?It takes 1700 J of work to stretch a spring from its natural length of 1 m to a length of 5 m. Find the force constant of the spring. The spring's force constant is N/m. (Type an integer or a simplified fraction.)

When the system is released, the ball traveled along the horizontal surface whose coefficient of kinetic friction is 0.203 and then up a frictionless plane inclined at 0=29.3° above the horizontal.

- Please asapKhufra works at a spring factory and he was assigned to test a certain spring, whose constant is 50 N/m, attached to a 50-kg block in an incline 30°. With the spring initially at equilibrium position, the block was pushed 0.3 meters up the incline by a 50-N external force applied parallel to the path. The coefficient of kinetic friction is 0.30. How much work is done by the spring (in Joules) on the block? (Please explain the solution)Hk=0.38. If the speed of the block v=7m/s when it leaves the inclined plane, determine the work done by the force of gravity. Take g =9.81m/s² and express your final result using one decimal place. A block of mass m=1.64kg is released from rest at an unknown height h. The coefficient of friction between the block and the incline oriented at an angle of 0=56° is m h т
