Regents Physics : Simple Motion Practice Set

What is the difference between speed and velocity?

• There is no difference

• Speed measures both magnitude and direction

• Velocity measures both magnitude and direction

• Speed is measured in miles per hour and velocity in m/s

A car travels between the 100. meter and 250. meter highway markers in 10. seconds. The average speed of the car during this interval is...

• 10. m/s

• 15 m/s

• 25 m/s

• 35 m/s

A 5-newton force directed east and a 5-newton force directed north act concurrently on a point. The resultant of the two forces is

• 5 N northeast

• 10. N southwest

• 7 N northeast

• 7 N southwest

A group of bike riders took a 4.0-hour trip. During the first 3.0 hours, they traveled a total of 50. kilometers, but during the last hour they traveled only 10. kilometers. What was the group's average speed for the entire trip?

• 15 km/hr

• 30. km/hr

• 40. km/hr

• 60. km/hr

Which two displacement vectors could result in a minimum value of 4.0 meters and a maximum of 28 meters when combined together?

• 10. m and 10. m

• 12 m and 8.0 m

• 12 m and 16 m

• 16 m and 8.0 m

A cannonball is fired with an initial velocity of 100. meters per second at an angle of 15.0° above the horizontal. What are the horizontal (vx) and vertical (vy) components of this velocity?

• vx = 65.0 m/s, vy= 76.0 m/s

• Vx = 96.6 m/s, vy= 25.9 m/s

• Vx = 25.9 m/s, vy= 96.6 m/s

• Vx = 76.0 m/s, vy= 65.0 m/s

Distance is to displacement as

• impulse is to momentum

• velocity is to acceleration

• speed is to velocity

• force is to weight

A car travels 90. meters due north in 15 seconds. Then the car turns around and travels 40. meters due south in 5.0 seconds. What is the magnitude of the average velocity of the car during this 20.-second interval?

• 5.0 m/s

• 2.5 m/s

• 6.5 m/s

• 7.0 m/s

1. A baseball pitcher throws a fastball at 42 meters per second. If the batter is 18 meters from the pitcher, approximately how much time does it take for the ball to reach the batter?

• 1.9 s

• 1. 2.3 s

• 0.86 s

• 0.43 s
