Answer:

Explanation:
Assume the stone consists of basalt, which has a density of 3.0 g/cm³.

Answer:
Acceleration a=0.5 m/s²
Explanation:
Given data
Mass m=12,900 kg=1.29×10⁴kg
Thrust of engine F=28,000 N=2.8×10⁴N
gravitational acceleration g=1.67 m/s²
To find
Acceleration
Solution
As we know that

The net force can be given as

From Newtons second law of motion we know that

Her average speed per hour, was 42.5 miles per hour
