The displacement of an object is given by x =sin2pi (t+0.01)m. Find amplitude of the oscillatory motion ,time period, maximum velocity , maximum acceleration and initial displacement

The specific weight of an unknown liquid is 12 400 N/me. What mass of the liquid is contained in a volume of 500 cm3? Use: the minimum value of gravity on the earth

Andrea has a particularly old bike, and she has not lubricated the chain or gears. This causes friction inside the gears as she rides. She begins coasting on flat ground at a speed of 10 m/s, and after a few seconds is only going 8 m/s. How much energy has been converted to heat?

A piano wire 0.5m longlong has a total mass of 0.01kg and is stretched with a tension ofof 800N. calculate the tension of the wire when it sounds it's fundamental note.

A hiker travels 4,5 km in a direction 12 degrees south of west and then 7,2 km in a direction 23 degrees west of south.

Determine the hiker’s overall displacement.

Draw each of the hiker’s individual displacement vectors on the same set of Cartesian axes, so that their initial points coincide at

the skin is the largest organ in the human body.For a human adult the average area of the skin surface is about 1.80m2 how much squared foot is this area

The viscosity of a fluid is to be measured by a viscometer constructed of two 3m long concentric cylinders.the inner diameter of the outer cylinder is 35cm, and the gap between the two cylinders is 0.14cm.the outer cylinder is rotated at 250rpm. and the torque is measured to be 1.8N determine the viscosity of the fluid

A platform diver has a kinetic energy of 12,000 n x m prior to landing in the water bucket. If her mass is 40 kg, what is her final velocity before splash?

A hiker travels 4,5 km in a direction 12 degrees south of west and then 7,2 km in a direction 23 degrees west of south.

Determine the hiker’s overall displacement.

Draw each of the hiker’s individual displacement vectors on the same set of Cartesian axes, so that their initial points coincide at

the origin:

:Determine the components of each of these vectors; then use them to find the resultant/overall displacement:

What is momentum
