Answer:
true
Explanation:
for example assume you are setting in a moving bus and when someone see you from the ground you are in motion but for some who is with you in the bus you are not in motion.
Answer: P= W/t so P=50/20 =2.5 W
Answer:
The final speed will be 8.02 rad/s.
Explanation:
Given that
radius ,r=5.9 m
Total acceleration = 18
Tangential acceleration = 12
Here particle is moving in circular path with varying linear speed.So there will be two acceleration ,one is radial acceleration and other one is tangential acceleration.
12=α x 5.9
ω=2.2 rad/s
θ=2πn
θ=2 x π x 1/8 rad
θ=π /4 rad
So the final speed will be 8.02 rad/s.
Hello!
The velocity function is:
a) 2.3 s earlier, we can make
t = -2.3 s, in relation to our initial time:
b) Now we can make
t = 2.3 s:
