In an elementary-particle experiment, a particle of mass m is red, with momentum mc, at a target particle of mass 2squrt (2m) . The two particles form a single new particle (completely inelastic collision). Find:
(a) the speed of the projectile before the collision
(b) the mass of the new particle
(c) the speed of the new particle after the collision
What is the minimum work needed to push a 800 -kg car 860m up along a 9.0 degree incline
It is then projected up the same plane with an initial speed 4.40 m/s. Explain how far up the incline will the block move before coming to rest?
A slab of copper of thickness b = 2.273 mm is thrust into a parallel-plate capacitor of C = 1.00×10-11 F of gap d = 10.0 mm, What is the capacitance after the slab is introduced
Suppose the speeder is traveling with a constant speed of 25m/s , and that the maximum acceleration of the police car is 3.1m/s2. find the maximum head-start distance the speeder can have
The minimum stopping distance for a car travelling at a speed of 30 {rm m/s} is 60 {rm m}, including the distance travelled during the driver's reaction time of 0.54 {rm s}.
White light, with frequencies ranging from 4.20×1014 Hz to 7.74×1014 Hz, is incident on a calcium surface. Calculate the lowest frequency for which no electrons are ejected
A speeder passes a parked police car at 30 m/s. At that instant, the police car starts from rest with a uniform acceleration of 2.44 m/s2.
