Look at the following diagram and determine which medium light travels SLOWER in, A or B, and why.

What is the weight of an object (on earth) that has a mass of 45 kg?

If the applied force on an object is 30 N and accelerates it at 3 m/s2, what is the mass of the object?

An aircraft weighing 18,692 N returns to the aircraft carrier and lands. It goes from 386 kilometers per hour (kph) to 0 kph in 4.9 seconds. What is the force required to bring the aircraft to a safe halt? (in N)?

If the acceleration of an object is 6 m/s2, how much does the object’s velocity change each second?

A 39.5 kg mg child on a sled slides down a hill reaching a speed of 8.92 meters per second how high was the hill in meters

A car begins from rest and reaches a speed of 20 m/s in 5 seconds. The acceleration of the car is      0 m/s/s     4 m/s/s     5 m/s/s     10 m/s/s

How large of a net force is required to accelerate a 1,592 kg car from rest to a speed of 13.7 m/s in a distance of 200 m

A bicycle moves from rest to 7.0 m/s in 3.6 seconds. What was the acceleration? Your Answer: Answer units

Mariana puts the pedal to the metal and increases her speed as follows. 0 miles per second at 0 seconds; 5 miles per second at 1 second; 10 miles per second: 15 miles per second at 3 seconds; and 20 miles per second at 4 seconds. What is the acceleration of Mariana's car?
