Three forces are applied on a particle of mass m= 15 kg located at the origin, as show below. The magnitudes are given to be FA = 15 N, FB = 35 N, Fc = 22 N, and the directions are 04 = 53°, measured from the negative x-axis, 03= 32°, measured from tl positive x-axis, and the direction of Fc is along the negative y-axis. a. Calculate the magnitude the net force on the particle. b. Calculate the direction...

An electron is a subatomic particle (m = 9.11 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.46 105 m/s to a final velocity of +1.93 106 m/s while traveling a distance of 0.041 m. The electron's acceleration is due to two electric forces parallel to the x axis: vector F 1 = +8.15 10-17 N, and vector F 2, which points in the -x direction. Find...

Two horizontal forces, P and Q, are acting on a block that is placed on a table. We know that P = 2.10î + 4.25k N but the magnitude and direction of Q are unknown. The block moves along the table. Assume there is no friction between the object and the table. Here the mass of the block is 4.55 kg. (a) Determine the force Q when the block moves with constant velocity. Express your answer in vector form. Q...

The position of a particle of mass m = 0.80 kg as a function of time is given by ⃗r = xˆi + yˆj = (Rsinωt)ˆi + (Rcosωt)ˆj, where R = 4.0 m and ω = 2πs−1. (a) Show that the path of this particle is a circle of radius R, with its center at the origin of the xy plane. (b) Compute the velocity vector. Show that vx/vy = −y/x. (c) Compute the acceleration vector and show that it...

please answer both questions ty so much
Two forces are acting on a 0.250 kg hockey puck as it slides along the ice. The first force has a magnitude of 0.400 N and points 35.0 north of east. The second force has a magnitude of 0.580 N and points 65,0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an...

A soccer ball of mass 0.36 kg is rolling with velocity <0, 0, 1.5> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N.s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.34 N in the direction opposite to the direction of the ball's time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked....

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...
