- A racing car reaches a velocity of 52 m/s north. It then uses its parachute and braking system to uniformly slow down and come to rest 5.5 seconds later. What was the displacement, in meters, of the racing car during those 5.5 seconds?A student drives 40 km south in an attempt to get to a science fair competition before realizing he missed the exit. He turns around and drives back north 15 km before arriving. The total time of travel was 0.75 hr. What is his speed? What is his velocity?To take off, a fighter jet accelerates at an average velocity of 9.45 m/s 2 and requires 5.9 seconds. After 260 meters of takeoff, what was the jet's final takeoff speed?
- A rock is dropped and takes 0.62 seconds to hit the ground. What was the impact velocity (velocity just before it hits the ground) of the rock?A rock is thrown straight down from a cliff at a velocity of 3.7 m/s and hits the ground below after 1.8 seconds. What was the velocity of the rock just before hitting the ground?Eg: A starts with an initial velocity of 10m/s and decelerates at -2 m/s^2. After comes to a full stop, it accelerates with an acceleration of 2 m/s^2 until it reaches 20 m. What is the average velocity in the entire trip?
- A ball is released from a crane, and hits the ground with a velocity of 17.8 m/s. How high up was the ball when it was released, and how much time did it take for it to hit the ground?A rock is held steady over a well and dropped. 4.9 seconds later, the sound of the rock hitting water is heard. Sound travels at a constant speed of 337 m/s. How deep is the well?A soccer ball starts from rest and accelerates with an acceleration of 0.385 m/s2 while moving down a 8.50 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 14.75 m, it comes to rest. (a) What is the speed of the ball at the bottom of the first plane (in m/s)? (Round your answer to at least two decimal places.) m/s (b) How long does it take to roll down the first plane (in s)? (c) What is the magnitude of the acceleration along the second plane (in m/s?)? m/s2 (d) What is the ball's speed 8.20 m along the second plane (in m/s)? m/s (e) What If? You change the angles of the two inclines in such a manner that the new acceleration down the first incline is a, new down = 2a initiel down and up the second incline is a, new un x initial up, What is the ball's speed 8.20 m up the second plane (in m/s)? 2 m/s
