A basketball is dropped from the top of a dam. If the ball is dropped from a height of 221 meters, how long does it take to hit the ground?
An airplane accelerates down a runway at 3.75 m/s2 for 32.4s until it finally lifts off the ground. Determine the distance traveled before takeoff.
Bill and Ted are walking on a trail. For the first 10.0 minutes of the walk, they are full of energy and travel at an average speed of 2.23 meters per second. They then slow their pace to 1.75 meters per second for the remaining 50 minutes of their walk. What is their average velocity?
A car is travelling at an average velocity of 30.5 m/s. If the car travels for 1 hour, how far does the car travel?
A person briskly walked 5.00 meters to the east and then 3.00 meters to the west in a total of 4.00 seconds. What was their speed?
A two parallel plate electrodes are separated by gap of 4 cm. For argon gas at 4 torr and 25 °C, the breakdown voltage is 822 V. Assume the constants A = 1.2 × 103 ion-pairs/m.torr and C = 2.0 × 104 V/m.torr. Determine:
(a) the second Townsend coefficient.
(b) the minimum breakdown voltage
(c) minimum pd value
(d) on which side of the Paschen curve does 822 V lies
a cube increases when the length of the edge increases
