Answer:
d) An object that is speeding up always has a positive acceleration, regardless of the direction it travels.
Explanation:
a ) a) An object that is slowing down while traveling in the negative x-direction always has a positive acceleration.
It has negative acceleration in the negative x-direction.
b) An object that is speeding up while traveling in the negative x-direction always has a positive acceleration.
It has a positive acceleration in the negative x-direction'
c) An object that is slowing down always has a negative acceleration, regardless of the direction it travels.
It has a positive acceleration in opposite direction.
e ) An object that is slowing down always has a positive acceleration, regardless of the direction it travels.
It has a positive acceleration only in opposite direction .
Answer:
test her prototype and collect data about its flight
Protons have positive charge on it. So, the sign of their Charge is positive. Yes
Hope this helps!
Calculate the 2 horizontal and verticle vectors of the velocity 78 m/s
the horizontal vector is what we want becoz the verticle vector is goin to be 0 at the max height.
the horizontal vector if 7.8Cos(17) = 7.46 m/s
So, now we have the velocity and we already have the mass, we can calculate KE,
.5(m)(v)^2
= 5779.8 J
I hope my answer is right, if not just comment, i will help u
