A 2.80 kg box is moving to the right with speed 8.50 m/s on a horizontal, frictionless surface. At t= 0 a horizontal force is applied to the box. The force is directed to the left and has magnitudeF(t)=( 6.00 N/s2 )t^2

a. What distance does the box move from its position at t=0 before its speed is reduced to zero?

b. If the force continues to be applied, what is the velocity of the box at 3.00 s ?

A 1.00-kg object slides to the right on a surface having a coefficient of kinetic friction 0.250. The object has a speed of vi = 3.00 m/s when it makes contact with a light spring that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance . The object is then forced toward the left by the spring and continues to move in that direction beyond the spring’s unstretched position....

A block of ice with mass 6.00 kg is initially at rest on a frictionless, horizontal surface. A worker then applies a horizontal force F⃗ to it. As a result, the block moves along the x-axis such that its position as a function of time is given by x(t)=αt2+βt3, where α = 0.210 m/s2 and β = 2.07×10−2 m/s3 .Calculate the velocity of the object at time t = 3.50 s .Calculate the magnitude of F⃗ at time t =...

A block of mass m = 0.53 kg attached to a spring with force constant 119 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.) The left end of a horizontal spring is attached to a vertical wall, and...
