This problem uses the ideal spring force in one dimension. F = -kx, where x is the deviation from equilibrium, and k is the spring constant. Calculate the particle's maximum speed (vmax), with these numbers: k = 2000 N/m = 2000 kg/s2 m = 5 kg (the mass of the particle) x0 = 0.2 m (the initial position) v0 = 5 m/s (the initial velocity)
A horizontal force is applied to an object weighing 392 N that causes its speed to increase uniformly from 0 m/s to 6 m/s in 3 seconds. If we disregard the friction value, calculate the applied force
A block, initially at rest, has a mass m and sits on a plane inclined at angle theta. It slides a distance d before hitting a spring and compresses the spring by a maximum distance of xf. If the coefficient of kinetic friction between the plane and block is uk, then what is the force constant of the spring?
A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28 degree incline. After sliding down the 110-m-long incline (on which the coefficient of kinetic friction is μk= 0.17), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which μk= 0.14) and comes to rest after a distance x. Determine BOTH the snowboarder's acceleration on the incline AND his acceleration on the flat surface. Then, determine x.
Three masses m1 = 3.5 kg, m2 = 10.5 kg and m3 = 7 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant of 228.9 N/m. the elevator is moving downward with a velocity of v = -2.7 m/s but accelerating upward with an acceleration of a = 5.4 m/s^2. Find the distance of the upper spring extended from its unstretched length and the force the bottom spring exerts on the bottom mass.
The friction force that a horizontal surface exerts on a 62 kg object is 23 N. If the initial speed of the object is 27 m/s, what distance will it slide before coming to a stop?
Same type of track as in the previous problem, this time with d = 2.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 4.46 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0 1.66 m 1.01 m -1.01 m -1.66 m
A net (unbalanced) external force of 100.0 N acts on an object of mass 20.0 kg whose initial speed is 10.0 m/s. The force acts in the opposite direction from the object's motion, and it acts for 1.00 s. What is the object's final speed, in m/s?

A pendulum is 0.890 m long, and the bob has a mass of 1.00 kg. At the bottom of its swing, the bob’s speed is 1.60 m/s. a. What is the tension in the string at the bottom of the swing? answer in N b. The tension is greater than the weight of the bob because of which of the following? its horizontal component is increasing from zero. the bob has zero acceleration. the bob has a downward acceleration, so the net Fy must be downward. the bob has an upward acceleration, so the net Fy must be upward.
A skydiver is at an altitude of 1520 m. After 10.0 seconds of free fall, he opens his parachute and finds that the air resistance, FD , is given by the formula FD = −bv, where b is a constant and v is the velocity. If b = 0.750, and the mass of the skydiver is 82.0 kg, first set up differential equations for the velocity and the position, and then find: (a) the speed of the skydiver when the parachute opens, (b) the distance fallen before the parachute opens, (c) the terminal velocity after the parachute opens (find the limiting velocity), and (d) the time the skydiver is in the air after the parachute opens.
(Each question reads 18pts and the magnitude g of the gravitational acceleration ⃗g is g = 9.81m/s2)Q1) A block of mass m = 1kg, to which a spring of spring constant k = 43N/m is attached, stands on a horizontal plane. If the spring attached to that block can be stretched horizontally with an amount of 14.8cm until the block skids, what is the coefficient of static friction between the block and the surface of the plane?
