The acceleration is zero.
Acceleration is by definition the change in velocity per unit time.
If the velocity of the girl is uniform at 1.5 m/s, then there is no acceleration.
Remember that velocity is a vector quantity and a vector can change in 3 ways
Magnitude only
Direction only
Both magnitude and direction.
Now the magnitude of velocity (speed) can stay constant while the direction is changing. This is the case in circular motion.
In the question above, it is mentioned that the girl is moving along a straight road. Therefore no change in direction of velocity.
Final Answer: No acceleration because of no change in velocity.
Answer:
Last week when I was going to a field trip I overslept and I had to run to school. As I got closer to the schools entrance I tripped and I got to school limping. When the teachers saw me they took me to the nurse where I told her how I hurt myself and in response the nurse told me that I just sprained my ankle. After that we got on the bus and we left to the zoo. As we got to the zoo I decided to get some souvenirs and the price was high. A sweatshirt cost $40, a stuffed dolphin cost $65 and a miniature ice skate rink cost $50 so I decided to leave the store. I prefer to rely on my memories and save my money because I was planning to eat at the sushi buffet that was across the souvenir store.
Narendra Modi is the prime minister of India
