Question

find the constant force necessary to accelerate a car of mass 1000kg from 15m/s to 20m/s in 10s against resistance of 270N ? pls show work (answer is 770N just in case to check)

ive been asking this question 4 times still no one answer . someone pls do .

a = (20-15)/10 = 0.5 m/s^2

F = m a

F = 1000 (0.5) + 270

F = 500 + 270

F = 770 N
