Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the stone is 0.2 kilograms and the acceleration is 10.0 meters per square second.
- m= 0.2 kg
- a= 10.0 m/s²
Substitute the values into the formula.
Multiply.
Convert the units.
- 1 kilogram meter per square second (kg*m/s²) is equal to 1 Newton (N)
- Our answer of 2 kg*m/s² is equal to 2 N
The force is <u>2 Newtons.</u>
The velocity of the combination of Jackie and the bicycle is 3.328 m/s.
Explanation:
From the given data the constant kinetic energy is 3.6 J. The mass of combination is 0.65 kg. To find the velocity of the combination of Jackie and the bicycle the formula is
KE = 0.5 x mv2.
To find velocity,
V2=ke/(0.5×m)
V=
v= 3.6/(0.5×0.65)
=
v= 3.328 m/s
Hence, the velocity of the combination of Jackie and the bicycle is 3.328m/s.
