A leopard is running with a velocity of 3 m/s. it then accelerates at 2 m/s² for 4 seconds. use the formula:
v = u + at
to work out the final velocity of the leopard.

please can people reply and help me thank you

Using the formula:

v = u + at

Here s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.

In this case, u = 3m/s, a = 2m/s^2, t = 4s and we want to find final velocity, v, s, v = u + at

v = 3 + 2(4) = 11m/s

Hope this helps!

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
