Two particles with masses 4m and 3m are moving toward each other along the x axis with the same initial speeds vi. The particle with mass 4m is traveling to the left, and particle 3m is traveling to the right. They undergo a head-on elastic collision and each rebounds along the same line as it approached. Find the final speeds of the particles.
A 600 turn solenoid, 25 cm long, has a diameter of 2.3 cm. A 10 turn coil is wound tightly around the center of the solenoid. If the current in the solenoid increases uniformly from 0 to 5.0 A in 0.55 s, what would be the induced emf magnitude in t..
how far did the last car travel before momentarily coming to a rest. A 3 kg block accelerates at a rate twice that of a 6 kg block. Is the net force acting on the 3kg block twice as large as that acting on 6kg block.
A point charge +6.7 uC is placed at the origin, and a second charge -3.6 uC is placed in the X - Y plane at (0.40 m , 0.55 m ). Where should a third charge be placed in the plane so that the net force acting on it is zero? Express your answers usi..
A 66.0 kg person throws a 0.0410kg snowball forward with a ground speed of 25.0 m/s. A second person, with a mass of 57kg, catches the snowball.
What is the current in amperes in a wire of radius. The parallel plates in a capacitor, with a plate area of 8.70 cm2 and an air-filled separation of 3.30 mm, are charged by a 8.90 V battery.
A crankshaft with a diameter of 3.0 cm , rotating at 2500 rpm comes to a halt in 1.50 s, What is the tangential acceleration of a point on the surface of the crankshaft
A standard baseball has a circumference of approximately 23 cm. If a baseball had the same mass per unit volume as a neutron or a proton, about what would its mass be?
The perspective provided by Multiple-Concept is useful here. The highest barrier that a projectile can clear is 15.60 m, while the projectile is launched at an angle of 23.0 ° above the horizontal. What is the projectile's launch speed.
When you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy, Determine the amount of water you lose to evaporation when running for 31 minutes at a rate that uses 400 kcal/h above your BMR
Several vectors in the x-y plane are shown in the figure with their tails at the origin of the coordinate system and with a label at their heads
Cheetahs, fastest of the great cats, can reach 45 in 2 starting from rest. Assume that they have constant acceleration throughout that time, find their acceleration (in (a) and (b) ) and the distance (in (c) and (d) ) Q2. They travel during that t..
