A 2.00-kg object is free to slide on a horizontal surface. The object is attached to a spring of spring constant 300 N/ m, and the other end of the spring is attached to a wall. The object is pulled in the direction away from the wall until the spring is stretched 50.0 mm from its relaxed position. The object is not released from rest but is instead given an initial velocity of 2.50 m/s away from the wall. Ignore...
You have two equal masses m1 and m2 and a
spring with a spring constant k. The mass m1 is
connected to the spring and placed on a frictionless horizontal
surface at the relaxed position of the spring. You then hang mass
m2, connected to mass m1 by a
massless cord, over a pulley at the edge of the horizontal surface.
When the entire system comes to rest in the equilibrium position,
the spring is stretched an amount d1 as shown...
I have three questions I need assistance on please: 1. To make an object start moving on a surface with friction requires (a) less force than it takes to keep it moving on the surface at constant velocity (b) the same force as to keep it moving on the surface at constant velocity (c) more force than it takes to keep it moving on the surface at constant velocity (d) a force equal to the weight of the object (2)...

An object of mass m = 1.70 kg is travelling on a horizontal surface. The coefficient of kinetic friction between the object and the surface is muk = 0.200. The object has speed v = 1 .35 m/s when it reaches x = 0 and encounters a spring. The object compresses the spring a distance d/2, stops instantaneously, and then travels back to x = 0 where it stops completely. Eventually you will be asked to find the spring constant,...
Please answer the four questions below. I attached the previous post. A 200. kg iceboat is accelerating in the +x direction on a frictionless frozen lake. ->a) What is the iceboat's acceleration in m/s2? ->b) At t = 0, the ice boat has an initial velocity of 2.00 m/s. What was the iceboat's initial momentum? (in kg m/s) ->c) What was the iceboat's initial kinetic energy? (in Joules) ->d) What is the kinetic energy after going through the 20.0 m...
I need help with the questions for Force Graphs and the

PHY213 Physics I PHY213 Online Lab 03 Lab 03: Forces and Motion Whoa! That's long way down PURPOSE In this experiment we will investigate the action of Forces and the resulting motion. THEORY Scalars are quantities that have only magnitude. Vectors are quantities that possess both magnitude and direction. Vectors, must be treated with direction in mind. Forces are...
I need help with my homework
1. M, and M; are two masses connected as shouwn in Fig 1. The paulley is ight and frctionless. (a) Find the mass Mi, given that M: (2.0kg) acoelerates upwards at 2.0m/sec, that e is 35., and that μ¡ is 0.35, (b) What is the tension? 2. Two blocks with masses m:-18.7 kg and m-91.0 kg, shown in the fig. 2, ane free to move. The coefficient of static friction between the blocks is...
A 3.00-kg object is free to slide on a horizontal surface. The object is attached to a spring of spring constant 300 N/m ,and the other end of the spring is attached to a wall. The object is pulled in the direction away from the wall until the spring is stretched 70.0 mm from its relaxed position. The object is not released from rest, but is instead given an initial velocity of 2.50 m/s away from the wall. Ignore friction....
