A car advertisement states that a certain car can accelerate from rest to 70 m/s in 7 seconds. Find the car’s average acceleration.
What is 10 m/s2?
What is displacement?
Straight-line distance from initial point to final point.
The slope of a distance-time graph.
What is speed?
The equation used to calculate average speed.
What is distance / time?
Define velocity.
Speed in a given direction.
A race car rapidly picks up speed on a straightaway. Its velocity is 4 m/s. But 3 seconds later, at the other end of the track, its velocity is 22 m/s. What is its average acceleration?
What is 6 m/s2?
Ryan is running 30 m South, 50 m North and 20 m West. What is his distance?
100 m
The slope of a displacement-time graph.
What is velocity?
Is speed a vector or scalar quantity?
Scalar
Is velocity a scalar or vector quantity?
Vector
A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration?
What is 2 m/s2?
Ryan is running 30 m South, 50 m North. What is his displacement?
20 m North
The speed of the object between 20 and 30 seconds.
What is 0 m/s?
How far does an airplane fly if it flies at a speed of 300 m/s for 10 seconds?
3,000 m
An object travels 15 meters South in 0.5 seconds. What's the velocity?
What is 30 m/s South?
A dog is running to catch a bird. He is running at a velocity of 15 m/s, but as he approaches the bird, he slows down to 3 m/s in 4 seconds. What is the dog's acceleration?
- 3 m/s2
A car drives 14 miles south, 3 miles east, and then 14 miles north. What is the cars distance? Displacement?
Distance = 31 miles
Displacement = 3 miles east
The velocity of the object between 20 and 28 seconds.
What is -2 m/s?
What is the speed of a car if it travels 300 m in 67 seconds?
4.48 m/s
What is the displacement of a car that drove with a velocity of 12.96 m/s east for 54 seconds?
700 m East
As a car approaches a red light, it's velocity is 28 m/s. It needs to come to a complete stop before it reaches the red light. If the car's acceleration as it slows down is -7 m/s2, how long will it take the car to come to a complete stop?
What is 4 s?
A car drives 3 miles east and then 4 miles north. What is the car's displacement?
Displacement = 5 miles NE
Describe the motion of the object on this graph.
The object travels at a constant velocity for 2 seconds. It stops for 5 seconds, then returns to it's original position with a constant velocity faster than it's initial velocity.
What is the distance a person ran in 48 seconds if their speed was 3.2 m/s?
153.6 m
How long will it take a rocket ship to reach the edge of the Earth's atmosphere, 100 km above earth's surface, if it has a velocity of 30,000 km/hr? Convert your answer to seconds.
0.2 seconds
