Question

13 what is the velocity of a toy car that rolls 350 cm towards a wall in 4.8 seconds? a 0.73 cm/s towards the wall b 72.9 cm/s towards the wall c 354.8 cm/s towards the wall d 1,680 cm/s towards the wall

Explanation:

Step1: Recall the velocity formula

Velocity \(v=\frac{d}{t}\), where \(d\) is distance and \(t\) is time.

Step2: Substitute the given values

Given \(d = 350\) cm and \(t=4.8\) s. Then \(v=\frac{350}{4.8}\approx72.9\) cm/s.

Answer:

B. 72.9 cm/s towards the wall
