A splinter starts from rest and uniformly accelerates at a rate of 2/2

1.	A splinter starts from rest and uniformly accelerates at a rate of 2/2 for 5.0 seconds. What is his final velocity?
Answer» Given: A sprinter starts from REST and uniformly accelerates at a RATE of 2 m/s² for 5.0 seconds. To find: Final velocities of man ? Calculation: Since the acceleration is constant, we can easily apply the equations of KINEMATICS in order to solve this question. Let final velocity be v, INITIAL velocity be U, acceleration be a and time be t. Applying 1st Equation of Kinematics: $\sf\therefore \: v = u + at$ $\sf \implies \: v = 0 + (2 \times 5)$ $\sf \implies \: v = 0 + 10$ $\sf \implies \: v = 10 \: m/ {s}^{2}$ So, final velocity of sprinter is 10 m/s.

Given:

A sprinter starts from REST and uniformly accelerates at a RATE of 2 m/s² for 5.0 seconds.

To find:

Final velocities of man ?

Calculation:

Since the acceleration is constant, we can easily apply the equations of KINEMATICS in order to solve this question.

Let final velocity be v, INITIAL velocity be U, acceleration be a and time be t.

Applying 1st Equation of Kinematics:

$\sf\therefore \: v = u + at$

$\sf \implies \: v = 0 + (2 \times 5)$

$\sf \implies \: v = 0 + 10$

$\sf \implies \: v = 10 \: m/ {s}^{2}$

So, final velocity of sprinter is 10 m/s.
