3. Compute the force of a small car, weighing 2,205 pounds, traveling 60 mph, that crashes into a steel pole and comes to a stop in 0.05 second. (For this to work, the computations must be all metric!) Then, you need to find acceleration, or actually car's deceleration i. e., the difference between its final speed and initial speed, at the moment of impact. (Once mass and acceleration are known, one can compute force in newtons. Show set-up. )

Astudent is working in the lab to determine how time affect impulse the student keeps the force the same in each row but changes impact the time some data is shown witch trial has the greatest a student is working in the lab to determine how time affect impulse the student keeps the fours the same in each row but change is the impact time some data shown witch trial has the greatest impulse

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

What does the law of conservation of mass state?
