Question

If a = 5m /s2 , t = 2 sec, v = 20 m /s then U = ?​

Answer 1

Answer:

200

Explanation:

becaus afer two and 20 ibs 200

Answer 2

The value of U is 10 m/s.

Given - a, t and v

Find - U

Solution - We will use first equation of motion to find u.

v = u + at

Keep the values in formula to find the value of u.

$20 = u + 5 \times 2$

Performing multiplication

$20 = u + 10$

$u = 20 - 10$

Performing subtraction

$u = 10$

Hence, the value of u is 10 m/s.
