The figure gives the acceleration a versus time t for a particle moving along an x axis. The a-axis scale is set by as = 12.0 m/s². At t = -2.0 s, the particle's velocity is 11.0 m/s. What is its velocity at t = 6.0 s? a (m/s²) as -2 0 2 t(s) 4

Two solid cylindrical rods AB and BC are welded together at B and loaded as shown. Knowing that the average normal stress must not exceed 150 MPa in either rod, determine the smallest allowable values of the diameters d₁ and d2. Take P= 85 kN. P 125 kN B 125 kN C 0.9 m 1.2 m The smallest allowable value of the diameter d₁ is The smallest allowable value of the diameter d₂ is mm. mm.

Westros, from Game of Thrones, has an area of approximately 6.73⋅106 miles26.73⋅106miles2.  Convert the area of Westros to km2 where 1.00 mile = 1.609 km.

a) What is the lenght of x? b) Findθ   c) Find ϕ

A surveyor measures the distance across a straight river by the following method: Starting directly across from a tree on the opposite bank, he walks x = 97.7 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is θ = 33.0 °. How wide is the river?

A small turtle moves at a speed of 697. furlong/fortnight. Find the speed of the turtle in centimeters per second. Note that 1.00 furlong = 220. yards, 1.00 yard = 3.00 feet, 1.00 foot = 12.0 inches, 1.00 inch = 2.54 cm, and 1.00 fortnight = 14.0 days.

The landmass of Sokovia lifted in the air in Avengers: Age of Ultron had a volume of about 1.98 km3.  What volume is that in m3?
