Asap

a) find the value of 3a + 4b when a = 17 and b = 9.
b) use the formula v= u + at to find the velocity, when
• the initial velocity is 3 m/s
• the acceleration is 1.5 m/s?
• the time is 7 seconds

a) The value of

b) The velocity is .

Step-by-step explanation:

Part a

Given:

and

Find the value of given expression =

Put a, b value in given expression

The value of

Part b

Given:

the initial velocity is

the acceleration is

the time is seconds

The given formula to find the velocity.

where ,

u = initial velocity

t = time

Put all the value in given velocity formula

Therefore, the velocity is .
