Problem Eight. A snowmobile is originally at the point with position vector 31.1 m at 95.5°
counterclockwise from the x-axis, moving with velocity 4.89 m/s at 40.0°. It moves with constant
acceleration 1.73 m/s² at 200°. After 5.00 s have elapsed, find the following.
9.) The velocity vector in m/s.
(A)=-4.38+0.185ĵ
(D) = 0.185 +4.38ĵ
(B)=0.1851-4.38ĵ
(E) = 4.38 +0.185ĵ
(C) v=-0.1851-4.38ĵ
(A)=-39.3-4.30ĵ
10.) The final position vector in meters.
(B)=39.3-4.30ĵ
(C) = -4.61 +39.3ĵ
(D) = 39.31 +4.30ĵ
(E) = 4.30 +39.3ĵ

One of the teachers kicks the ball back up to the children as shown in the figure below. The playground is 6.10 m above the parking lot, and the school building's vertical wall is h = 7.40 m high, forming a 1.30 m high railing around the playground. The ball is launched at an angle of 8 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall.

An electron microscope can view such objects using an electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of electric and magnetic fields that control the electron beam. As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity ₁ = vi. As it passes through the region x = 0 to x=d, the electron experiences acceleration a = ai +a, where a and a, are constants. For the case v, = 1.67 x 107 m/s, ax = 8.51 x 1014 m/s², and a = 1.50 x 10¹5 m/s², determine the following at x = d = 0.0100 m. (a) the position of the electron y, = 2.60e1014 m (b) the…arrow_forward
