The projectile maintains its horizontal component of speed because there's nothing exerting any horizontal force on it. <em>(b) </em>

Gravity has no effect on horizontal motion.

a is the proper answer as you are deniying air resistance and only receiving gravity

What is the resistance of a 1.3 m copper wire ( = 1.7 10-8 m) that has a cross-sectional area of 8.36 10-6 m2?

Scilla [17]

The resistance of a piece of wire is given by
$R= \frac{\rho L}{A}$
where
$\rho$ is the material resistivity
L is the length of the wire
A is its cross-sectional area

Substituting the data given by the problem, we can find the value of the resistance of the wire:
$R= \frac{\rho L}{A}= \frac{(1.7 \cdot 10^{-8} m)(1.3 m)}{(8.36 \cdot 10^{-6} m^2)}=2.6 \cdot 10^{-3}\Omega$

How do I find deceleration

Mars2501 [29]

Deceleration isn't a term in physics; you can have positive acceleration which is speeding up and negative acceleration which is slowing down
Use newton's law F = ma
a = F/m
