Answer: 2.1 × 10^7 m/s
Please see the attachments below
28m/s
Given law,
⇒ x(t) = 2t + 3t³
Where, t = 2s
Then,
⇒ x(2) = 2(2) + 3(2)³
⇒ 4 + 3(8)
⇒ 4 + 24
⇒ 28 m/s
Acceleration is 28m/s
My guess for this one would be; 400 N
My reasoning would be; it starts at 0 on both X and Y, if you need to get to 1.00 meters thats 4/4. 1/4 of 1.00 is .25, and on .25 its on 100 so multiply it by 4 to make 1.00 and you get 400 N
