Well, F = ma
and a= change in vel / change in time
= (2-0 ) / 1 = 2 m^2/s
so, F= 4* 2 = 8 N
and W = F.S = 8 * 2 = 16 J
hope it helped
Answer:
starting position: 3 m
velocity: 3 m/s
Explanation:
at t=0 position= 3 m
velocity: (delta)position/(delta)time
(delta=change in)
velocity= (15-3)/(4-0)
velocity= 12/4
velocity= 3 m/s
Explanation:
Her cells will not work well when they have low levels of oxygen.
Answer:
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
