I got all but this problem, I A 0.145-kg baseball is pitched at 42.0 m/s. The batter hits it horizontally to the pitcher at 58 m/s. A. Find change in momentum? Is it =.145*58-(-.145*42)=1.45-kg m/s? B. If bat and ball are in contact for 4.6 x 10-4 s, what is average force ...

**Physice....help please**

not understanding how to do this. A certain storm cloud has a potential of 1.00x10^8 V relative to the tree. If during a lightning storm, 50C of a charge is transfered through this potential differnce and 1.00% of the energy is absorbed by the tree, how much sap can be boiled ...

An example of the neutron absorption reaction is . 1 0 n+10 5 B-->7 3 Li+ 4 2 He The rest masses of each particle in atomic mass units (u) are 1 0 n= 1 u 10 5 B=10 u 7 3 Li =7 u 4 2 He= 4 u where 1u=1.66x10^-27 kg. calculate Q Q= in MeV I have the same question please ...
