Asap plzzzz

A uniform bar of length 24 m and mass 1 kg
is attached to a wall with a hinge that exerts
a horizontal force H, and a vertical force Hy
on the bar. The bar is held by a cord that
makes a 90° angle with respect to the bar and
44° with respect to the wall.
1 kg
24 m
What is the magnitude of the horizontal
force H on the pivot? The acceleration of
gravity is 9.8 m/s².
Answer in units of N.

A trough is 5 meters long, 1.5 meters wide, and 1 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 1 meters, and base, on top, of length 1.5 meters). The kg trough is full of water (density 1000- ). Find the amount of work in m3 joules required to empty the trough by pumping the water over the top. (Note: Use g = 9.8 as the acceleration due to gravity.) s2 5m 1.5m 1m
Keep the track tilted at 7∘∘ with the horizontal, at let the cart roll downwards. The length of the track is 75 cm. Starting from zero speed at the top of the track, what will be the speed of the cart as it reaches the bottom? Write your answer in m/s, and ignore friction. Mass of the cart = 250 grams.
An ideal Spring of negligible mass is 12,00 cm long when nothỉng is attached to ît, When you hang a 3,15-kg weight from it, you measure ſts length to be 13.40 cm, If you wanted to store 10,0 J of potential energy in this spring, what would be ſts total length?
A 47-kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.2 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
A 58-kg pole vaulter running at 10 m/s vaults over the bar. Her speed when she is above the bar is 1.3 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
Suppose that the average U.S. household uses 14100 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 1690 kg car 15.8 m into the air, how long would it take? car: S Using the same rate of energy consumption, how long would it take to lift a loaded Boeing 747 airplane, with a mass of 3.90 x 10° kg, to a cruising altitude of 9.42 km? airplane: S
Hi there, quick true or false question. If you double the mass of an object that is at some elevated position, above a reference level, youd double it's gravitational potential energy. True or False Thanks!!
