Three major branches of natural science

A car is traveling with a constant speed of 30.0 m/s when the driver suddenly applies the brakes, causing the car to slow down with a constant acceleration. The car comes to a stop in a distance of 120 m.

What light is NOT in the visible light spectrum

A visible violet light emits light with a wavelength of 4.00 * 10-7 m. Calculate the frequency of the violet light.

What is the momentum of a 2 kg ball traveling at 2m/s

A constant force is exerted for a short distance on a block of mass that is initially at rest on a horizontal frictionless plane. This force gives the block a certain final speed v.

A football quarterback is moving straight backward at a speed of 3.00 m/s when he throws a pass to a player 20.0 m straight downfield. (a) if the ball is thrown at an angle of 25.

Simone is walking her dog on a leash. The dog is pulling with force of 34 N to the right and simone is pulling backward with a force of 16 N

An object moves with velocity v (t) = t^2-8t+7 a) write a polynomial expression for the position of the particle at any time t greater or equal to zero.
