A car is moving with constant speed of 60 km/h. Calculate its acceleration.

Give an example of a collision in real life. Use the law of conservation of energy to describe the transfer of momentum. Be sure and discuss the momentum before and after the collision occurs.

An object has a weight of 5.10 N at sea level, where the acceleration is 9.81. What is the acceleration due to gravity on the object if it is placed in a spaceship 1,000km above sea level, where gravity exerts a force of 3.81N on the object

What kind of tide does the observer experience as he passes though a tidal bulge

The position of an object connected to a spring varies with time according to the expression x (5.2 cm) sin (8.0 pt).

Where does the energy lost from trophic level to trophic level go?

During combustion, a fuel's electromagnetic energy is converted into thermal energy.

Explain why glucose is important to a cell

4. How far does a car travel in 90 seconds if it is traveling at a speed of 55 m/s?

Total energy input is 1400 and my efficiency is 80% so what is the useful energy output in jules?

What is the force of gravity acting on a 2000-kg spacecraft when it orbits two Earth radii from the Earth's center (that is a distance r=6380 km above the Earth's Surface. The mass of the Earth is 5.98 x 1024 kg.
