Question
In order to go from rest to 100m/s in 20 s, an object must accelerate at?Question 5Answera.10 m/s2b.100 m/s2c.50 m/s2d.20 m/s2e.5 m/s2
Solution
The acceleration of an object can be calculated using the formula:
Acceleration = Change in Velocity / Time
In this case, the object is going from rest (initial velocity = 0 m/s) to 100 m/s in 20 seconds. So, the change in velocity is 100 m/s.
Substituting these values into the formula gives:
Acceleration = 100 m/s / 20 s = 5 m/s²
So, the object must accelerate at 5 m/s² to go from rest to 100 m/s in 20 seconds. Therefore, the answer is e. 5 m/s².
