The 25-Mg boxcar A 16m/s to the right is coasting on the horizontal track when it encounters a 9-Mg car B coasting at 2m/s toward it. If the two cars meet and couple together, determin common speed in m/s just after the coupling. Please see details below. Rounding numbers to 2 decimal places at the end.
A 5.0-kilogram grenade lying motionless on the ground explodes into three pieces. (It's not a very sophisticated grenade.) A 2.0-kilogram piece flies off at 18 meters per second and 110 degrees. A 1.7-kilogram piece flies off at 31 meters per second and 270 degrees. What is the velocity of the third piece? Include units in your answers.
A fast train bump into a slow train going the same direction, and they get coupled together. The fast train was initially going 6.93 meters per second and the slow train 3.1 meters per second. What is the final speed (in meters per second) once the two are coupled?
-20. Two cyclists, Mike and Josh, simultaneously started toward each other from two towns d = 24 km apart. Josh rode at vj = 25 km/h, and Mike %3D at UM = 15 km/h. The moment they start, a fly also starts from Josh towards Mike and after reaching Mike, immediately returns towards Josh. The fly continues back and forth motion between the cyclists till the cyclists meet. Air speed of fly is UF = 30 km/h and the wind blows always towards Mike with a constant velocity u = 10 km/h. Find the total distance s flown by the fly. Sneedometer shows speed and odometer shows distance travelled, both
Arthur and Betty start walking toward each other when they are 100. m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. Their dog, Spot, starts from Arthur's side at the same time and runs back and forth between them. By the time Arthur and Betty meet, what is Spot's displacement?
Space debris left from old satellites and their launchers is becoming a hazard to other satellites. One can estimate how long such a collision lasts; if an object of length l is traveling at a velocity v, it will cover a distance l in a time equal to l / v. This is the approximate time of interaction for an object being smashed against another object. Parts (a) and (b) are already completed.Part (a) Calculate the speed (in m/s) of a satellite in an orbit 940 km above Earth’s surface. v = 7360 Part (b) Suppose a loose rivet is in an orbit of the same radius that intersects the satellite’s orbit at an angle of 90°. What is the speed (in m/s) of the rivet relative to the satellite just before striking it? vtot = 10410 Part (c) Given the rivet is 2.95 mm in size, how long will its collision with the satellite last? In this approximation, the rivet is completely destroyed and the collision does not slow the rivet down. Part (d) If its mass is 0.485 g, what is the average force it exerts…
The acceleration of a rocket is a = -bV, where V is the speed of exhaust gases coming out of the thruster. What are the SI units of b?
A 500kg car moving to the north at 45m/s crashes head-on into a 600kg car that is moving the south at 23m/s. When they crash, they stick together. At what velocity do the two cars move after the collision?
people love to play with balls nowadays especially during quarantine as theres not much to do. lets say we have a ball that hits another ball that is at the rest. after they hit and smash each other, the first ball moves 4m/s on the platform and makes an angle of 25 degrees while the other ball has a speed of 3m/s.. FIND a)get the angle b3tween da d1rection of motion of da second one (ball) and the original direction of motion of da first one. b) find da original sp33d of the first one c)let me ask u this question. is the kinetic energy is being conserving?
I was standing on the side of a 10-m foot bridge, holding a ball while watching a car approaching the bridge at uniform speed. When the car was 15 meters away from where I was standing, the ball that I was holding slipped in my hand and the car arrived at the bridge when the ball hit the ground. What was the speed of the train? ( Assume that the final velocity of the ball is NOT zero)
A passenger in a train moving at 30 m/s passes a personstanding on a station platform at t=t'=0. Twenty secondsafter the train passes, the person on the platform determines thata bird flying along the tracks in the same direction as the trainis 800m away. Five seconds later, the bird is 850maway. Assume a constant velocity for all involved. a) Draw a coordinate system indicating the motion of bird andtrain in the grame of the observer on the platform b) What are the coordinates of the bird as determined by thepassenger? c) Find the velocity of the bird as determined by the observeron the platform and the train passenger.
