Formula 1 cars should be fast to win a race. How much should the power (in horsepower) of a Formula 1 racing car should be to provide energy in a horizontal level racetrack in 3 minutes
A car has a mass of 1500 kg moves with a speed of 40 m/s. If the car speeds up to 50 m/s. How much is the work done by the car engine?
the distance between two consecutive threads on micrometer screw gauge is
A 0.75 kg board of length 2.60 m initially rests on two supports as shown. What maximum distance, x, from the right-hand support can a 1.20 kg bird walk before the board begins to leave the left-hand support
If you change the mass and volume does the density of a fluid changes?
Solve: 1. D= 1000kg÷ 4m^3
2. D= 1000kg÷ 2m^3
3. D= 600kg÷ 3m^3
4. D= 400kg÷ 3m^3
A 62kg shell is shot from cannon.
What is the gravitational potential energy id tye shell reaches an450m height
What is the change in potential energy of the system when the shell falls to a height if 300m
A 0.600 kg mass oscillates at the end of a spring with stiffness of k= 300 N/m. The initial amplitude is 0.500 m. The damping force is proportional to the velocity, "-av".
A. If the amplitude decreases from 0.500 m to 0.350 m in 2.500 s, what is the damping constant "a" ?
Note: The answer in letter A should be 7.44 × 10^-2 kg/s
