Studied by 0 peopleA cart moving across a level surface accelerates uniformly at 1.0 meters per second2 for 2.0 seconds. What additional information is required to determine the distance traveled by the cart during this second interval?
The initial velocity
The graph represents a linear motion of a car. The car has the largest displacement in…
DE
What does the image represent?
Force in equilibrium
A car is moving with a constant speed of 20. meters per second. What total distance does the car travel in 2.0 minutes? (Hint: convert min to seconds)
2400m
The vector diagram below represents the velocity of a car traveling 24 meters per second 35° east of north.
What is the magnitude of the component of the car’s velocity that is directed eastward?
14 m/s
What do these graphs represent?
The vertical motion of an object falling freely
What is the acceleration of the car at t = 5.0 seconds?
0.0 m/s²
What does this graph represent?
The motion of an object in equilibrium
As a car is driven south in a straight line with decreasing speed, the acceleration of the car must be
Directed northward
An object is in equilibrium. Which force vector diagram could represent the force(s) acting on the object?
What quantities are scalar?
Speed and work
The components of a 15-meters-per-second velocity at an angle of 60.° above the horizontal are (Hint: dr
13 m/s vertical and 7.5 m/s horizontal
What quantity is scalar?
Mass
Which term determines a scalar quantity?
Time
What is the total distance the object falls during the first 3.0 seconds? (Hint: make a triangle)
12m
A rock is dropped from a bridge. What happens to the magnitude of the acceleration and the speed of the rock as it falls? [Neglect friction.]
Acceleration remai and the speed increases
Scalar is the vector as…
Speed is to velocity
