A beam of protons is moving toward a target in a particle accelerator. This

im trying to study for my exam by doing problems, however im stuck with this one. any help is appreciated

beam constitutes a current whose value is 0.39A. (a) How many protons strike the target in 14 seconds? (b) Each proton has a kinetic energy of 3.9 x 10-12 J. Suppose the target is a 14-gram block of metal whose specific heat capacity is 1100 J/(kg Co), and all the kinetic energy of the protons goes into heating it up. What is the change in temperature of the block at the end of 14 s?

a/ use the charge on a proton, knowing an ampere is a coulomb per second.

number=current/chargeproton *timeinseconds

b. Ke total=number*KEeach=mass*c*changetemp
solve for change in temp
