Question

A student 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 1

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.

Answer 2

The velocity v is 312 m/s

Further explanation

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem !

This problem is about Kinematics.

We will solve it in the following way

Given:

d = 35.0 m

t = 9.00 s

vo = 3.00 m/s

Unknown:

v = ?

Solution:

For this problem, we only need to substitute the data given to the equation.

$v = dt - v_o$

$v = 35.0( 9.00 ) - 3.00$

$v = 315 - 3$

$v = 312 ~ m/s$

Conclusion:

The velocity v is 312 m/s if d = 35.0 m , t = 9.00 s , and vo = 3.00 m/s
