A 0.500-kg potato is fired at an angle of 80.0° above the horizontal from a PVC pipe used as a "potato gun" and reaches a height

of 110.0 m. (a) Neglecting air resistance, calculate the potato’s velocity when it leaves the gun. (b) The gun itself is a tube 0.450 m long. Calculate the average acceleration of the potato in the tube as it goes from zero to the velocity found in (a). (c) What is the average force on the potato in the gun?

Answer:

Explanation:

a ) Maximum height H = 110 m

Formula for maximum height in a projectile

= u² / 2g where u is initial velocity

110 = u² / 2g

u² = 110 x 2g

u = 46,43 m / s

b)

v² = u² + 2as

v = 46.43

u = 0

s = .45 m

a = acceleration

46.43² = 2 x a x .45

a = 2395 m/s²

c ) Average force

= mass x acceleration

.5 x 2395

= 1197.5 N.

PLEASE HELP !! A 10 ohm resistor is connected to a 9V battery how much current is flowing through the circuit?
kompoz [17]

Resitance (R)= 10 Ohm

Potential difference (V) = 9V

V= IR

I= V/R

I= 9/10

I= 0.9 Ampere

Therefore 0.9 Ampere of current is flowing through the circuit.

If launched at the right speed, what could eventually happen to objects launched from Newton's theoretical cannon on the top of
Nadusha1986 [10]
If the speed is higher than the orbital velocity, but not high enough to leave Earth altogether (lower than the escape velocity), it will continue revolving around Earth along an elliptical orbit. (D) for example horizontal speed of 7,300 to approximately 10,000 m/s for Earth.
