A drinking fountain shoots water out from a height of 3.5cm above its basin. The water follows an arc which extends 15 cm horizontally before hitting the basin. The arc reaches a maximum height of 11cm above the basin. Determine the time a single drop spends in the air? The initial speed of the water and angle at which it shot out of the fountain?
A 2.46×10^4 rocket blasts off vertically from the earth's surface with a constant acceleration. Throughout the motion considered in the problem, suppose that remains constant. Inside the rocket, a 15.10 instrument hangs from a wire that can support a..
Consider a tungsten filament in a light bulb. After the bulb has been on for an hour, how has the resistance in filament changed (if at all).
Compute the numerical value for acceleration
A 55 kg person is riding in a hot air balloon and scale shows this person's weight too be 549N. the acceleration of gravity at the location of the balloon is known to be 9.79 m/s/s.

An archer shoots an arrow horizontally at the target 14 m away. The arrow is aimed directly at the center of target, but it hits 59 cm lower.
Analysis of Physics, Two pistons push down on the fluid filling two cylinders connected by a narrow hose, as shown in the figure. The area A1 is 1 square inch, and the area A2 is 10 square inches
Solve for Vmax. (d) If V0 is less than some value Vmin, a value of the height of the building does not exist that allows both balls to hit the ground at the same time. Solve for Vmin.
if ellis is on earth, mario is on mars and monique is on the moon. they all have a mass of 50kg. they all jump off a trampoline. who will jump the highest. find what is the Tension T2 in the left.
A pendulum consists of a 4.98kg mass on the end of a 0.873 m string. The mass is pulled aside so the string makes an initial angle with the vertical of 12.5o. The mass is then released with initial speed of 2.10m/s upward and perpendicular to the rop..
A disk of radius R = 9 cm is pulled along a friction less surface with a force of F = 15 N by a string wrapped around the edge. At the instant when d = 28 cm of string has unwound off the disk, what is torque exerted about the center of the disk.
