1) A 100 Newton force acts on an object to the right at the same time a second force of 180 N acts to the left. Calculate the net, or resultant force on the object. Give the answer rounded to 1 decimal place and remember that forces in the +x direction are positive and forces in the -x direction are negative. 2) Calculate the acceleration of a 18 kg mass, if a 100 N force acts to the right and...
A single force acts on a 0.54 kg particle-like object in such a way that the position of the object as a function of time is given by x = 5.0t -0.71t2 + 3.0, with x in meters and tin seconds. Find the work done on the object by the force from t=0 tot = 9.1 s. Number 198 Units
A constant 12.0-N net force acts for 3.0 s on a 3.0-kg object. What is the object's change of velocity? 12 m/s 4 m/s 3 m/s 5 m/s
When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with a massive 26 kg the acceleration of the object is 3 m/s^2. This is the same force acts upon another object with mass is 39 kg what is the objects acceleration.
An object of mass 0.61 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.8 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval.
An object of mass 0.53 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.1 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. N
A single force acts on a 0.92 kg particle-like object in such a way that the position of the object as a function of time is given by x = 3.2t - 2.6t2 + 3.1t3, with x in meters and t in seconds. Find the work done on the object by the force from t = 0 to t = 3.2 s.
Impulse is defined as the change in momentum of an object in a collision. Impulse = mass * δv = mass * (vfinal - vinitial). Given these values: mass = 0.2986 [kg] and velocityinitial = 0.383 [ms-1] and velocityfinal = -0.3064 [ms-1], what is the Impulse? Use three significant figures and answer in Ns. Note: 1 [kg ms-1] = 1 [Ns] (Ns = Newton Second) and 1 [Newton] = 1 [kg ms-2]. What does impulse equal?
6) At one instant, force F 4.0j N acts on a 0.25 kg object that has position vector (2.0-2.0k) m and velocity vector (-50i+5.0k) m/s. About the origin and in unit vector notation, what are (a) the object's angular momentum and (b) the torque acting on the object?
At one instant, force F 4.7i N acts on a 0.374 kg object that has position vector (7.80-7.80f) m and velocity vector V - (-1.11+1.11K) m/s. About the origin and in unit- vector notation, what are (a) the object's angular momentum and (b) the torque acting on the object?
