Sarah wants to find out how much time it would take to drive from her home to New York. At an average, she would drive at 55 miles per hour. If the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)? O 13 hours 21 hours 29 hours 34 hours
The velocity of an object in free fall increases downwards with time
- Please find attached the correct graph showing velocity as a function time, with the positive direction to be upwards.
Reason:
The known parameters are;
Location where the rocks are released; Earth
The time at which rock Y is released = A few seconds after rock X is released.
Required:
To select the graph that shows the vertical velocity of rock, <em>x</em>, as a function of time.
Solution:
Let <em>t </em>represent the time after which rock x are released, with the positive direction being upwards, we have;
- The equation for the velocity of x is v = -9.81·t
With the above equation, the graph of the vertical velocity of rock x is plotted with MS Excel.
