A proton is projected in the positive x direction into a region of uniform electric field Earrowbold = (-5.40 multiplied by 105) i hat bold N/C at t = 0. The proton travels 6.20 cm as it comes to rest.
(a) Determine the acceleration of the proton.
(b) Determine the initial speed of the proton.
(c) Determine the time interval over which the proton comes to rest.
A steel wire with mass 20.5 g and length 1.29 m is strung on a bass so that the distance from the nut to the bridge is 1.10 m. Compute the linear density of the string
A 2200 kg sport utility vehicle travelling at 86 km/h can be stopped in 0.15 s if it hits a concrete wall. Presume a 60 kg person was in the car that hit this wall. The velocity of the person equals that of car both before and after the crash, and..
