I was given this as a practice problem:
A 1,000 kg car accelerates from rest to 25.0 m/s in 7.50 s. What is the Average power?
So far, I know that P= FD/t F=ma
m=1000kg
initial velocity = 0
final velocity = 25.0 m/s
t = 7.50 s
how do I find the acceleration? thx
sorry for the triple posting. I didn't know it was sending. I noticed that my answers were half of what they should be. PART A: For the average velocity on the way to they prey, I used (0 km/h + 18km/h) / 2. When I looked at the answer, it was showing that d = Average Velocity x t =...
I have a physics midterm tomorrow and this is the only problem that I cannot figure out. Thanks for the help!
The black mamba is one of the world's most poisonous snakes, and with a maximum speed of 18.0 km/h, it is also the fastest. Suppose a mamba waiting in a hide-out sees prey and begins...
