Answer: Velocity=8.26m/s
Explanation:
Acceleration=Finial velocity (V) - Initial velocity (u) ÷ Time
that is, a=v-u/t
a=1.2m/s², v=?, u=5.5m/s, t=2.3s
From a=v-u/t, make v the subject of the formula
v=at + u
v=(1.2* 2.3) + 5.5
v=2.76+5.5
v=8.26m/s
Answer:
Hey!
Well according to scientific data and analysis, it started to break up about 175 - 200 million years ago!!

HOPE THIS HELPS!!
Answer:

Explanation:
From the question we are told that:
Initial Speed 
Time 
Angle
Generally the Newton's equation for motion is mathematically given by



Answer:
n = 2.0686
Explanation:
When an unpolarized ray of light is reflected on a surface, the reflected ray is partially polarized, complete polarization occurs when it is true that between the transmitted and reflected ray one has 90, the relationship is
n = so tea
let's calculate
n = tan 64.2
n = 2.0686
Answer:
Initial velocity will be 1.356 m/sec
Explanation:
Let the initial speed = u
Angle at which rubber band is launched = 37°
Horizontal component of initial velocity 
Time is given as t = 1.20 sec
Distance in horizontal direction = 1.30 m
We know that distance = speed × time
So time 


So initial velocity will be 1.356 m/sec
