Acar initially contains just its driver. the combined mass of car and driver is 869 kg. when the gas pedal is pushed down all the way, the car reaches its maximum acceleration of 5.6 m/s2.if the driver then picks up three of his friends, the combined mass is increased by 300 kg. what is the maximum acceleration possible in units m/s2 now if the force provided by the engine remains the same as before? round to one decimal place.

4.2 m/s²

Explanation:

m = combined mass of car and driver = 869 kg

a = maximum acceleration reached by the car with driver in it = 5.6 m/s²

Force provided by the engine is given as

= ma

= (869) (5.6)

= 4866.4 N

M = Combined mass of car, driver and his three friends = 869 + 300 = 1169 kg

a' = maximum acceleration reached with friends in the car = ?

Force provided by the engine remains same and is then given as

= M a'

4866.4 = (1169) a'

a' = 4.2 m/s²

come closer and become far apart and become steam/gas

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
