<h2>Circular path i.e 1</h2>
Explanation:
If the driver steer into circular path , the acceleration of car will be
acceleration = velocity²/radius of circle
Because the velocity and radius of circle are both constant at all points . Thus the acceleration will also remain constant .
In case 3 and 4 , the radius of path changes . Because velocity is constant . Therefore the acceleration will not remain constant
That completely depends on your speed and the trajectory (path) you choose.
The Apollo missions took about 3 days each way.
The New Horizons spacecraft passed the moon within a couple of hours after it was launched.
1. The time taken for the car to reach a velocity of 60 m/s is 8.57 s
2. The distance travelled during the time is 257.14 m
<h3>What is acceleration? </h3>
The acceleration of an object is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
- a is the acceleration
- v is the final velocity
- u is the initial velocity
- t is the time
1. How to determine the time
- Initial velocity (u) = 0 m/s
- Acceleration (a) = 7 m/s²
- Final velocity (v) = 60 m/s
- Time (t) =?
a = (v – u) / t
Thus,
t = (v – u) / a
t = (60 – 0) / 7
t = 8.57 s
2. How to determine the distance
- Initial velocity (u) = 0 m/s
- Acceleration (a) = 7 m/s²
- Final velocity (v) = 60 m/s
- Distance (s) = ?
v² = u² + 2as
60² = 0² + (2 × 7 × s)
3600 = 0 + 14s
3600 = 14s
Divide both sides by 14
s = 3600 / 14
s = 257.14 m

Distance between the centers of the two objects are the second object
Answer:
Yes since it is changing direction
