Answer:
At focus
Explanation:
A concave mirror is converging in nature. In a mirror, concave in nature, the rays which are parallel to the principal axis are supposed to be coming from very large distances or we assume the source to be placed at infinity for such rays which are parallel to the principal axis.
These rays, parallel to the principal axis, coming from infinity, converges at the focus of the mirror concave in nature after reflecting from the concave mirror
Well, I think it kinda depends on how long the "extended period" is.
If the extended period is a week, a month, or a few months,
then I'd call it a 'cold wave'.
If the extended period is like 100 years or more, then you're
starting to talk 'ice age'.
The formula for potential energy is mass x height x gravitational force. Your mass is 5.3 kg and your height is 6.6 meters. The gravitational force on earth is 9.8 m/s. That means your answer is 5.3 x 6.6 x 9.8 and that equals 342.804
Answer
given,
initial speed,u = 0 m/s
final speed,v = 24.8 m/s
time, t= 5.9 s
a) acceleration,
a = 4.20 m/s²
b) distance to travel in that time
using equation of motion
v² = u² + 2 as
24.8² = 0² + 2 x 4.20 x s
8.4 s = 615.04
s = 73.22 m
the motorcycle will travel 73.22 m
