Astudent solving a physics problem for the velocity of an object has applied appropriate physics principles and obtained the expression v=dt−v0, where d=35.0meter, t=9.00second, and v0=3.00meter/second. what is the velocity v?

Answer : 312 meters/second.

Explanation : As the given expression is v=dt−v0;

where v is to be found and rest all values are given;

d is 35 meters

t is 9 seconds

and v0 is 3 seconds

So, when we substitute these values in the equation we get,

v = (35 meters X 9 seconds) - 3 seconds

v = 312

therefore, velocity v will be equal to 312.
