10. Two forces act on a 3 kg object, the gravitational force and a second, constant force. The object starts from rest and in 2.1 s is traveling with a velocity of (20ˆi + 10ˆj) m/s. At what angle does the second force act with respect to the ˆi direction? Assume the gravitational force acts in the −ˆj direction. (the answer is 56.8 ◦)
Besides the gravitational force, a 2.40-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (5.10î − 3.30ĵ) m, where the direction of ĵ is the upward vertical direction. Determine the other force. (Express your answer in vector form.)
Can you please give me the whole solution for this
question!
Thanks
2. According to Newton's Law of Universal Gravitation, the gravitational force on an object of mass m that has been projected vertically upward from Earth's surface is F( is the objer s distan boe he urfac at time t, Ris Earth's radius, ngR (x+R)2 and g is the acceleration due to gravity. Also, by Newton's Second law, mgR2 (x +R)2 dv F = mal = m dt =...

Two horizontal forces act on a 5.6 kg chopping block that can slide over a frictionless kitchen counter, which lies in an xy plane. One force is ( 1 )=(6.0 î +10.0 j) N.. Find the acceleration of the chopping block in unit-vector notation when the other force is (2)=(-6.0 i +4.01N, O A a =(2.5 î +2.5jm/s2 OB. å=(6i + 4ſ)m/s2 oca=2.5 î m/s2 D. a=2.5 j m/s2
1) An object feels the impact of 3 forces. The mass of the object is 2.82 kg. The object has an acceleration of 1.93 m/s2 at 28.6 degrees N of E. Force 1 is 11.0 N at 62.4 degrees S of E and Force 2 is 18.8 N at 57.5 degrees S of W. What is the magnitude and direction of Force 3? (Assume that no additional forces act on the object.)Do not use energy ideas in your solution. 2)...
Three forces act on a 15-kg object. Force 1 is 12 N directed along the positive x-axis. Force 2 is 18 N directed along the -y-axis. And Force 3 is 22 N directed exactly midway between the +x=axis and -y-axis. a) Draw a free body diagram clearly labeling the forces. b) Find the net force on the object in both unit vector and polar notation. c) Draw this force on your diagram.
The figure below shows a block with mass m = 5.3 kg pulled up a ramp inclined at an angle of 6 = 28° with a force of magnitude F = 33 N parallel to the ramp. m (a) If there is no friction between the block and the ramp, what is the magnitude of the block's acceleration (in m/s2)? 1.485 Draw a free-body diagram. What forces act on the block? Let the x-axis be parallel to the incline. What...

Two forces are acting on a 6.89-kg object that moves with acceleration 9.31 m/s2 in the positive y-direction. If one of the forces acts in the positive x-direction and has magnitude of 12 N, what is the magnitude of the other force in N?
