olga55 [171]

Answer:

a)  1955.6 J

b) 1955.6 J

c) 2607 N

d) 110373 J

Explanation:

a) Kinetic\ Energy = \frac{1}{2} mv^2 = \frac{1}{2} \times  \frac{4.2}{1000} \times  965^2 = 1955.6 J

b) Work done on bullet should be increase in KE = 1955.6 J

c) Work done = Force \times displacement = KE of bullet

              F = \frac{1955.6}{0.75} = 2607 N

d) Work done to stop = KE = F_{stop} \times d_{stop}

F_{stop} = \frac{1955.6}{\frac{1.5}{100}} = 110373 J
