A particle moves on a straight line and cover a displacement x metres in time t seconds. If the displacement is in form of equation given below. Find its acceleration after 2 seconds. x = 5t^3 - t^2 + 1

58 m / s²

Step-by-step explanation:

The rate of change of displacement is velocity v

The rate of change of velocity is acceleration a , thus

v = = 15t² - 2t , then

a = = 30t - 2

After 2 seconds

a = 30(2) - 2 = 60 - 2 = 58 m/ s²

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
