Answer:
4. Force = 178.6 Newton.
5. Acceleration = 2.28 m/s².
6. Force = 178.6 Newton.
Explanation:
4. Given the following data;
Acceleration = 3.8 m/s²
Mass = 47kg
Force = mass * acceleration
Force = 47 * 3.8
<em>Force = 178.6 Newton. </em>
5. Given the following data;
Force = 785N
Mass = 345kg
Acceleration = force/mass
Acceleration = 785/345
<em>Acceleration = 2.28 m/s²</em>
6. Given the following data;
Acceleration = 6m/s²
Force = 32N
Mass =force/acceleration
Mass = 32/6
<em>Mass = 5.33 kilograms </em>
Straight linear path
Explanation:
If the universe were completely empty with just one object which is solid moving sphere through the space at a speed of 100km/s, it will move along on a straight path.
An object will continue on a straight path or at rest unless acted upon by an external force. This is the first law of newton.
- Since there is no other mass or body in the universe, it will move along in a straight line.
- Our planet and other bodies moves in parabolic path and elliptical orbits because they are attracted by the gravitational forces of other bodies.
- Any body with mass will attract other bodies and makes it move round it.
- The body with the less mass will orbit in the vicinity of the larger mass.
- But if we have just one body out there, there is no attraction from any other body, it will continue along it's straight path.

Answer:
4.55 m/s
Explanation:
The frequency is defined as the number of rotations in one second
So, f = 2.03 Hz
r = 0.357 m
The tangential speed is
v = r ω = r x 2 x 3.14 x f = 0.357 x 2 x 3.14 x 2.03 = 4.55 m/s
