what is a force ?

An object is held in the hand at a height of 2.5 m above the ground and released

a) how long will it take to reach the ground

b) with what velocity will it hit the ground?

A force 𝐹⃗ = (6𝚤̂ - 𝚥̂) N acts on a particle that undergoes a displacement 𝑑⃗ = (3𝚤̂ + 𝚥̂) m. Find (a) the dot product 𝐹⃗ • 𝑑⃗ and (b) the angle between 𝐹⃗ and 𝑑⃗. 

Vector 𝐴⃗ has a magnitude of 5.00 units, and vector B ⃗ has a magnitude of 9.00 units. 

The two vectors make an angle of 50.0° with each other. Find 𝐴⃗ •B ⃗. 

Due to a force field, a particle of 10kg moves along a space curve where position vector is given in a function of time by (4t^3)i ̂+(5t^2)j ̂+(t^2)k ̂

a. ) What is the velocity vector?

i ̂ j k ̂

b. ) Calculate for the momentum.

i ̂ j k ̂

The dryer of a washing machine goes into its spin cycle from rest and gains a speed of 5.0 rev/s in 3.0s. When the lid is opened, the dryer slows down and finally stops in the 7.0s. Compute the angular acceleration during the first 3.0s and the last 7.0s. Through how many revolutions does the dryer turn before coming to stop?

At what temperature do Celsius and Fahrenheit are equivalent in value? Prove your answer.

AU-tube of uniform cross-sectional area, open to the atmosphere, is partially filled with mercury. Water is then poured into both arms. If the equilibrium configuration of the tube is as
