A stressed out Mom just purchased a cup of Starbucks coffee. The bus she is riding on to work goes around a sharp curve. Even though she holds the cup still, the coffee still splashes out. Which word explains this phenomenon?
The phenomenon that explains the coffee splashing out of the cup is called "inertia."
Consider the situations below. Which of these is the BEST example of Newton's 1st Law (inertia)? (1 point)
a. A tennis player throws the tennis ball into the air for a serve and the ball falls to the ground.
b. A bird takes flight from the ground.
c. You go down a steep hill in a sled and it feels like your stomach is going up into your throat.
d. Tom uses a cane to walk across the road.
The best example of Newton's 1st Law (inertia) among the given situations is (d) Tom using a cane to walk across the road.
A roller coaster begins at the top of a hill. If it accelerates at the rate of 2 m/s and has a mass of 2000 kg, what net force is acting on it? (Force=mass x acceleration)(1 point)
To calculate the net force acting on the roller coaster, we can use the formula Force = mass x acceleration. Given that the acceleration is 2 m/s² and the mass is 2000 kg, we can substitute these values into the formula:
Force = 2000 kg x 2 m/s²
Force = 4000 kg*m/s²
Therefore, the net force acting on the roller coaster is 4000 kg*m/s².
A roller coaster begins at the top of a hill. If it accelerates at the rate of 2 m/s and has a mass of 2000 kg, what net force is acting on it? how many newtons is it? (Force=mass x acceleration)(1 point)
To find the net force in newtons (N), we can use the formula Force = mass x acceleration. Given that the acceleration is 2 m/s² and the mass is 2000 kg, we can substitute these values into the formula:
Force = 2000 kg x 2 m/s²
Force = 4000 kg*m/s²
Therefore, the net force acting on the roller coaster is 4000 kg*m/s², which is equivalent to 4000 Newtons (N).
Matt is walking at 1.25 miles per hour to the east. Jaime is walking at 1.25 miles per hour to the south. Which statement describes the movement of Matt and Jaime?(1 point)
The movement of Matt and Jaime can be described as:
Matt is moving horizontally to the east at a speed of 1.25 miles per hour.
Jaime is moving vertically to the south at a speed of 1.25 miles per hour.
Therefore, Matt's movement is along the x-axis (east-west direction), and Jaime's movement is along the y-axis (north-south direction).
