Ответ:
John F Kennedy proposed a legislation that later became the Civil rights Act of 1964 . He expressed that civil rights are moral issues and affirmed that the pursuit of racial equality was a just cause. By supporting equality and civil rights movement with his speech on civil rights, he played a crucial role in shaping his legacy as a proponent of civil right. However at the beginning he was afraid that Concerned that dramatic actions would alienate legislators in the heavily segregated American South, so that he supported civil rights and desegregation with caution. Kennedy offered stronger support for civil rights, including the enactment of new legislation that would ensure desegregation in the commercial sector when he felt the pressure of those impatient African-American as a result of the lack of social progress which was leading to further tension.

-200 N
Explanation:
Force: This can be defined as the product of mass and acceleration The S.I unit is N
The expression for force is given as
F = m(v-u)/t Equation 1
Where F = Impact force, m = mass of the lorry , v = Final velocity of the lorry , u = initial velocity of the lorry, t = time
Given: m = 6000 kg, v = 0 m/s (the lorry was stopped), u = 0.5 m/s, t = 1.5 s
Substitute into equation 1
F = 6000(0-0.5)/1.5
F = -300/1.5
F = -200 N.
Note: The negative sign shows that the impact force act in opposite direction to the initial motion of the lorry
