Question

If the object has a mass of 10kg and starts from rest, how fast is it going at t=3 seconds?

Answer 1

The object is going at a speed of 29.4 m/s at t=3 seconds.

Step-by-step explanation:

To calculate the speed of an object at a given time, we can use the equation v = gt, where v is the final velocity, g is the gravitational acceleration, and t is the time.

Since the object starts from rest, its initial velocity is 0 m/s.

Using the equation v = gt, we can substitute g = 9.8 m/s² (constant for gravitational acceleration) and t = 3 s (given in the question).

Plugging in these values, we get

v = 9.8 m/s² * 3 s = 29.4 m/s.
