8) A mass of 9 kg is at rest on a frictionless incline which inclined at 26 degrees. A force of 10 Newtons is applied parallel to the incline, up the incline and another of 23 Newtons is applied perpendicular to the incline, away from the incline. What is the acceleration of the mass in m/s2? If up the incline include a negative sign.

A mass of 7 kg is placed on an incline with friction and no additional forces acting on it and it begins to slide at some angle when the angle is slowly increased as discussed in class. Now, the same mass is placed on the same incline, but an additional force of 28 Newtons is applied to it perpendicular from the incline, away from the incline (it's always in that direction). As the angle of the incline is slowly increased,...

1) A mass of 12 kg is at rest on a horizontal surface. One force of 33 N is applied at an angle of 32 degrees below the horizontal (in the +x direction), and a force of 14 N is applied vertically upward (perpendicular and away from the surface). What is the acceleration (in the x direction) of the mass in m/s2? If in the -x direction, include a negative sign.

A mass of 6 kg is placed on an incline with friction and no additional forces acting on it and it begins to slide at some angle when the angle is slowly increased. Now, the same mass is placed on the same incline, but an additional force of 17 Newtons is applied to it parallel to the ground away from the incline (it's always in that direction... also it's parallel to the ground, not the incline.). As the angle of...

A mass of 7 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 23 degrees below the horizontal, force 2 has a magnitude of 19 N and is applied vertically downward, force 3 has a magnitude of 3 N and is applied vertically upwards, and force 4 has a magnitude of 21 N and is applied in the-x direction to the object. When these forces are applied to the object, the object moves 9...

A mass of 5 kg is placed on an incline with friction which is inclined at an angle of 52 degrees. The coefficient of static friction is 0.84 and the coefficient of kinetic friction is 0.58. No additional forces are acting on the mass. What is the amount of friction acting on the mass in Newtons?
Question 6 7 pts A mass of 5 kg is moving across a frictionless surface at...
Question 6 7 pts A mass of 5 kg is moving across a frictionless surface at 13 m/s in the +x direction. It collides (perfectly) ELASTICALLY with a second mass of 9 kg moving in the -x or +x direction. After the collision, the 9 kg mass is moving at 3 m/s in the +x direction. If the collision took 0.03 seconds, what is the average force acting on the 5 kg mass in Newtons? It's a force, so if...

Question 13 13 pts A box of mass 0.8 kg is being pulled up a slope that is inclined by 60° compared to the horizontal. The tension in the rope pulling the box is 40 N and the rope is parallel to the incline. The slope is NOT frictionless and the coefficient of kinetic friction between the box and the slope is 0.35. Round off your answers to two decimal places. (a) What is the magnitude of the weight of...

2. A 40.0 kg wagon is towed up a hill inclined at 17.5° with respect to the horizontal, The tow rope is parallel to the incline and has a tension of 542 N. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. (a) How fast is the wagon going after moving 73 m up the hill? (b) What is the magnitude of the normal force acting on the wagon? 3. A 5.00 kg...

7, A block of mass 4.00 kg is released from rest near the top of an inclined plane, where θ 30.00. It slides with friction down the incline and then contacts and compresses an ideal spring that is rigidly mounted parallel to the incline near the bottom. The spring has a force constant of 500.0 N/m and it compresses a maximum distance x. If d = 200 meters and 0.300 meter, what is the coefficient of friction between the block...
