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
