14 % 1 question 8 of 42 an aeroplane's engines provide a force of 30,000n as it accelerates down the runway. the mass of the aeroplane is 4000kg. work out the acceleration of this aeroplane.

Given that,

Force F= 30,000 N

mass m= 4000 kg

acceleration = ?

since,

F= ma

a= F/m

a= 30,000/4000

a= 7.5 m/s²

acceleration of the given aeroplane will be 7.5 m/s².

the answer is mosques. they are an important part of islamic culture.

not too sure thinking all accelerations are pointed down
