This isi 5 points but whatever
if x=-4, y=3 and z=2
2(-4)²-2(2)⁴+(3)²-(-4)²+(2)⁴=
2(16)-2(16)+9-(16)+16=
32-32+9-16+16=
0+9+0=
9
First find the mass.
Since weight force is 48N, and acceleration due to gravity is 9.8 m/s^2,
weight force = mass*acceleration due to gravity,
mass = weight/acceleration
mass = 48N / 9.8 m/s^2
mass = 4.9 kg
Now you find the force needed to accelerate to 3.0 m/s^2.
Force = mass*acceleration
Force = 4.9kg * 3.0 m/s^2
Force = 14.7 N
mo, since you can't round integers unless it specifies otherwise
