In 1997, the Thrust SSC, a turbofan powered vehicle, achieved the land speed world record of 760.34 mph (1,223.65 km/h) and became the first car to break the sound barrier. If it took 1 minute for the Thrust SSC to reach its top speed, what was the average acceleration during that time?
What is a= 5.67 m/s2
How far away must a 19.6 N weight be placed on the left of a fulcrum to balance a 9.8 N weight 0.4 meters on the right?
What is 0.2 m
Consider less than two desirable options. In the first, you are driving 30 mph and crash head on into an identical car also going 30mph. In the second option, you are driving 30 mph and crash head on into a stationary brick wall. In neither case does your car bounce back from the thing it hits, and the collision time is the same in both cases. Which of these two situations would result in a greater impact force on your car.
What is, the force will be the same in both cases so neither would result in a greater impact
What is the acceleration of the 5 kg box that has a 25 N force and 50 N force applied both right?
What is 15 m/s2
A 45 kg skier is going at +8.2 m/s down an icy ski run when she suddenly falls and starts sliding on her back (in the same direction she was going). Exactly 3.0 s after falling her velocity has changed to +3.1 m/s. How far has she slid down the hill from where she fell? Assume that the acceleration is constant.
What is 16.95 m
