A typical jetliner lands at a speed of 140 mi/h and decelerates at the rate of (12.5 mi/h)/s. If the jetliner travels at a constant speed of 140 mi/h for 1.1 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
Two objects attract each other gravitationally with a force of 2.5×10-10 while they are 0.60 apart. Their total mass is 5.0. Find out their individual masses.
A curve of radius 40 m is banked for a design speed of 100 km/h. If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely create the curve?
A runner accelerates to a velocity of 4.15 m/s due west in 1.50s. His average acceleration is 0.640 m/s^2, also directed due west. What was his velocity when he began accelerating.
