Question

Charilanda is jogging at 2 m/s when she sees the ice cream truck. She speeds up at a rate of 1 m/s/s. When she reaches the truck, she is going 5 m/s. How long does it take to get to the truck?

Answer 1

the time it took Charilanda to get to the truck is 3s.

Step-by-step explanation:

Given;

initial velocity of Charilanda, u = 2 m/s

final velocity of Charilanda, v = 5 m/s

acceleration of Charilanda , a = 1 m/s²

let her time of motion = t

`a = (v-u)/(t) \\\\t = (v-u)/(a) \\\\t = (5-2)/(1) \\\\t = 3 \ s`

Therefore, the time it took Charilanda to get to the truck is 3s.
