2. While coming to a stop, a car leaves skid marks 120 m long on the highway. Assuming the car slows down at a rate of 6.2 m/s2, how long does it take for the car to come to a complete stop? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units : m, m/ s, s, m/s/s) Blank 1 - - - - Blank 2- - - - - 3. A penny is dropped from the top of a building 99.4 m high. What is the velocity of the penny just before striking the ground? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/ s, s, m/ s/s) Blank 1: - - - - Blank 2- 4. A lightweight plane must reach a speed of 33 m/s for takeoff. How long of a runway is needed if the plane has a constant acceleration of 3.0 m/s2? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, s, m/s/s) Blank 1- - - Blank 2- - - 5. How much distance can a runner cover if, starting from rest, he reaches a speed of 21.0 m/s in a time of 9.2 s? Round your answer to the nearest whole number and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/ s, 5, m/s/s) Blank 1 - - Blank 2 - - - 6. While coming to a stop, a car leaves skid marks 125.0 m long. If the car was initially traveling at a rate of 36.2 m/s, what was the car's acceleration while stopping? Round your answer to two decimal places and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/ s, s, m/s/s) Blank 1- Blank 2- 7.A ball is tossed vertically into the air. If the ball reaches a maximum height of 15 meters, what was its initial velocity? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, s, m/s, mph) Blank 1- - Blank 2 - - 8. A car, which is initially at rest, accelerates to 26.4 m/s in 6.2 s. Find the car's acceleration. Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, m/s/ s )
