Question

a = 2+²+t+1 find 'v' form 3to 5 sec​

Answer 1

i hope you are solve the problem

Answer 2

Answer:

75.33m/s

Explanation:

a = 2t²+t+1

dv/dt = 2t²+t+1

dv = (2t²+t+1)dt

v = {⁵(2t²+t+1)dt

³

v = [2t³/3+t²/2 +t]⁵

³

v = [2(5³)/3+5²/2+5]-[2(3³)/3+3²/2+3]

v = 250/3+25/2+5-18-9/2-3 = 250/3-8 = 226/3

v = 75.33m/s.
