Physics 20: ENTIRE COURSE REVIEW QUIZ

A soccer player runs 10.0[left], stops, sprints 25.0m[right] and then 8.5m[left]. His displacement from his original position is:

A penny is dropped from rest from a tower that is 0.553 km tall. What is the velocity of the penny right before it hits the ground?

A ball is thrown straight into the air from a roof with an initial speed of 6.00 m/s. The ball reaches the ground in 3.35 s. The final velocity and height of the roof are:

A baseball is thrown 30 m[W] from the third base to the second base. It is then thrown 30 m[N] to the first base. What is the resultant displacement?

What variable is always the same for the horizontal and vertical components of projectile motion?

A cannonball is fired horizontally at a speed of 120 m/s from a tower that is 50.0 m high. The time it would take for the cannonball to hit the ground would be [blank_start]4.95[blank_end] s. (three sig digs)

Label the graphs for the different kinds of motion

Fill in the blanks for the types of forces: Net force: [blank_start]Vector sum of forces acting on an object[blank_end] Normal force: [blank_start]Force that is perpendicular to a surface[blank_end] Applied force: F[blank_start]orce that goes w the direction of motion[blank_end] Friction force: Fo[blank_start]rce that opposes the direction of motion[blank_end] Tension force: [blank_start]Force that comes from other source[blank_end](eg.rope) Gravitational force: [blank_start]Force that attracts objects together[blank_end]

A racecar is timed as it passes two points on a race track. Its speed at those two points is 43.2 m/s and 68.7 m/s. If the car requires 2.00 s to travel between these two points, its acceleration(rounded to 3 significant digits) would be [blank_start]12.8[blank_end] m/s^2

A block is moved up a frictionless inclined plane by a force parallel to the plane. At the foot of the incline, the block is moving at 1.00 m/s. At the top of the incline, 0.850 m above the lower end, the block is moving at 4.00 m/s. The block has a mass of 1.20 kg. So that must mean that the block had [blank_start]19.0[blank_end] J of work done on it.
