Question

How much force is needed to accelerate a 80 kg rider and her 250 kg motorcycle at 4 m/s2? A) 320 N B) 1000 N C) 1030 N D) 1320 N

Answer 1

Heya friend!!❤

Well this is so simple. first add up the masses of the rider and the motorcycle as force will act on the combined mass of the rider and the motorcycle. so we get 80 + 250=330 kg. now going according to the formula F=ma we get the force equal to 330 multiplied by the acceleration 4m/s2 i.e. 330*4=1320 kgm/s2 or 1320 N.
so, the correct option is D.

Answer 2

Question :-

How much force is needed to accelerate a 80 kg rider and her 250 kg motorcycle at 4 m/s² ?

Answer :-

D ) 1320 N.

Salutation :-

Here , Total Mass ( m ) = ( mass of motorcycle + mass of the rider )

= ( 250 kg + 80 kg )

= 330 kg

Acceleration ( v ) = 4 m / s²

•°• Force = Mass × Acceleration

= 330 × 4 N

= 1320 N [ • Required Answer ]
