A5000.0-kg car goes from 0 m/s to 70 m/s in 3600 seconds. what is the accelera
then find the force involved in that acceleration?

given:

mass = 5000 kg

u (initial velocity) = 0 m/s

v (final velocity) = 70 m/s

time taken to change velocity = 3600 s

acceleration = v - u / t

a = 70 - 0 / 3600

a = 70 / 3600

a =  0.0194 m/s2 (approx)

given: mass = 5000 kg

acceleration = 0.0194 (found in 1st part)

force = mass * acceleration

f = ma

f = 5000*0.0194 = 97 N

therefore the acceleration will be 0.0194 m/s2

and the force involved in acceleration will be 97 N
