Answer: 490N

Explanation:

Newton is the unit for force. Force = mass x acceleration

F=N m=50kg a=9.8 (earth's acceleration of gravity)

F=50X9.8

F≈490N

Answer:

Acceleration $a=0.455m/sec^2$

Explanation:

We have given that the force by the motor $F=2.51\times 10^3N=2510N$

Resistive force by the water $F=1.88\times 10^3N=1880N$

So net force $F_{NET}=2510-1880=630N$

Mass of the boat = 1384.1 kg

According to newton's second law F=Ma, here M is mass and a is acceleration

So $630=1384.1\times a$

$a=0.455m/sec^2$
