A car's speed changes from 10m/s to 35m/s in 15.0s along a straight road while moving in one way. Find the magnitude of the acceleration of the car during this period.​

1.67 m/s²

Explanation:

Applying,

a = (v-u)/t Equation 1

Where a = acceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.

From the question,

Given: v = 35 m/s, u = 10 m/s, t = 15.0 s

Substitute these values into equation 1

a = (35-10)/15

a = 25/15

a = 1.67 m/s²

Hence the acceleration of the car is 1.67 m/s²

Racial segregation in the United States Armed Forces, which has included separation of white and non-white American troops, quotas, restriction of people of colour troops to support roles, and outright bans on blacks and other people of colour serving in the military, has been a part of the military history of the United States since the American Revolution. Each branch of the Armed Forces has historically had different policies regarding racial segregation. Although Executive Order 9981 officially ended segregation in the Armed Forces in 1948, following World War II, some forms of racial segregation continued until after the Korean War. The US government complied with an Icelandic government request not to station black soldiers on the US base in Keflavík, Iceland until the 1970s and 1980s when black soldiers began to be stationed in Iceland.
