Example Question #261 : Mcat Physical Sciences
If an object is dropped from a height of 450 meters above Earth, what is its velocity just before impact?
67m/s
6.7m/s
45m/s
95m/s
95m/s
First calculate the time it takes to hit the ground using the equation .
We can plug in values (including acceleration due to gravity) and solve for t.
t = 9.49s
Next, find the final velocity with the equation .
Example Question #263 : Mcat Physical Sciences
A sports car has a mass of . What must its acceleration be to generate over a distance of ?
This question will require us to deal with work and force.
We are given the mass of the car, the work energy generated, and the distance. Using these values, we can solve for the acceleration.
Example Question #262 : Mcat Physical Sciences
Which of the following is not a vector quantity?
Momentum
Displacement
Velocity
Weight
Kinetic energy
Kinetic energy
Kinetic energy is calculated by squaring velocity (which we know is a vector). This eliminates its vector properties making kinetic energy a scalar value. All other answer choices are vector quantities.
