Emmy kicks a soccer ball up at an angle of 45° over a level field. She watches the ball's trajectory and notices that it lands two seconds after being kicked, about 20 m away to the north. Assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. Consider only the time that the ball is in the air, after being kicked but before landing. Take "north" and "up"...
2.2 INTEGRALS OF VECTOR FUNCTIONS; PROJECTILE AND CIRCULAR MOTION 4. A projectile is fired northward out to the sea from the top of a cliff 264 ft high. Assuming that the r-axis is pointing east and y-axis is pointing north. The projectile's initial velocity vector is v(0) experiences in flight an eastward acceleration of 3 ft/s2 due to spin. Find the projectile's velocity and position vectors t seconds after the projectile is fired. (0, 92, 14). In addition to a...
Problem 1. (point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring feet. The ball is started in motion from the equilibrium position with a downward velocity of 9 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity on feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that this...

This stretches the spring The ball is started in motion from the equilibrium position with a downward velocity of 8 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second) Suppose that after t seconds the ball is y feet below its rost position. Find y in terms of t....
Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...
Problem 18: An electrically charged base ball of mass 150g travels with a constant velocity of 89.5mph on a horizontal straight line in a southwestern direction, suspended against gravity by the magnetic force due to the earth's magnetic field. The earth's B-field is pointing straight north, horizontally, with a strength of 60 T. The earth's gravitational acceleration is 9.81m/s2 and 1mile = 1,609m. Neglect air resistance. Find y, the electric charge (amount and sign!). carried by the ball. Hints: (1)...
(1 point) A soccer ball is thrown straight up a distance of 6.0 m and retums to your hand. Neglecting air resistance, you know that OA. the accelcration was constant throughout its motion B, the acceleration wฮ5 upward on the way up and downward on the way down О С, the speed was zero at the maximum height, but the velocity was never zero. D. the ball took longer to go up than come down. E. the velocity was constant...

PLEASE ANSWER BOTH PROBLEM SETS PLEASE ANSWER BOTH (1 point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 528 feet. The ball is started in motion from the equilibrium position with a downward velocity of 7 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find...
(1 point) A mass weighing 8 lb stretches a spring 3 in. Suppose the mass is displaced an additional 11 in in the positive (downward) direction and then released with an initial upward velocity of 2 ft/s. The mass is in a medium, that exerts a viscuouse resistance of 1 lb when the mass has a velocity of 4 ft/s. Assume g 32 ft/s is the gravitational acceleration (a) Find the mass m (in lb.s/ft) (b) Find the damping coefficient...
