Q. A wrecking ball (weight 5400-N) is supported by a boom, which may be assumed to be uniform and has a weight of 3200-N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and the horizontal is 32 degrees, and the angle between the boom and horizontal is 48 degrees. Find out the tension in the support cable and find out the magnitude of force exerted on the lower end of the boom by the hinge.

#### What would the period of the system be

what would the period of the system be. When a particular mass-spring system is started by stretching the spring 5 cm, one complete oscillation takes 2 seconds.

#### What was initial speed

A hollow sphere is rolling along a horizontal floor at 7.0 m/s when it comes to a 39^circ incline. How far does it go up the incline before coming to a stop and roll back down.

#### How far does each ball travel horizontally

If the two balls started rolling at the same time at a point 1.2 m behind the edge of the table, will they reach the floor at the same time? define.

#### Research topic of heat loss in a cylindrical pipe

Evaluate the heat loss per meter for each of the combinations you can figure out. Summarize the result in a graphical way, such as a table, such that they are easy to read and understand.

#### The coefficient of volume expansion of coffee

The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker.

#### Establish the mechanical energy of the system

A cylindrical container 1.6 m tall contains mercury to a certain depth d. The rest of the cylinder is filled with water. If the pressure at the bottom of cylinder is two atmospheres, what is the depth d.

#### How much heat it take to increase the temperature

Old MacDonald had a farm, and on that farm he had a gate (see below). The gate is 3m wide and 1.8m high, with hinges attached to the top and bottom. The guy wire makes an angle of 300 with the top of the gate and is tightened by a turn buckle to a..

#### What is the speed of ejected electrons

If a 4-engine jet accelerates down the runway at 5m/s2 and 3 of the jet engines fail, how much acceleration will the other one produce.

#### How far is point horizontally from the end of the ramp

how far is this point horizontally from the end of the ramp. A skateboarder shoots off a ramp with a velocity of 6.2 m/s, directed at an angle of 61° above horizontal. The end of the ramp is 1.5 m above the ground.

#### What are the amplitude of the subsequent oscillations

Calculate its average velocity for the entire trip. A horse canters away from its trainer in a straight line, moving 120 m away in 15.0 s. It then turns abruptly and gallops halfway back in 5 s.

#### What is the tension in the rope at that point

How thick should the air layer be between two flat glass surfaces if the glass is to appear bright when 530 light is incident normally.

#### What speed does the man obtain as a result

A person with perfect pitch sits on a bus bench listening to the 441-Hz horn of an approaching car. If the person detects a frequency of 479 -Hz, how fast is the car moving.
