Answer:
Great question! To solve this problem you just need a bit of simple math. The short answer is 60 m/s
Explanation:
To solve this, you must first set up your equation.
540km/2.5hr * 1000m/3600s
You would set it up this way because there are 1000 meters in a km and 3600 seconds in an hour. This
540000m/9000s
This simplifies down to
60m/s
Answer:
.
Explanation:
By Newton's Second Law, the acceleration of an object is proportional to the net force on it. In particular, if the mass of the object is , then
.
Rewrite this equation to obtain:
.
In this case, the assumption is that the force is the only force that is acting on the object. Hence, the net force on the object would also be
Make sure that all values are in their standard units. Forces should be in Newtons (same as , and the acceleration of the object should be in meters-per-second-squared (). Apply the equation to find the mass of the object.
.
