A cannonball is tired with an initial speed of 40m/s and a launch angle of 30degrees from a cliff that is 25m tall. a. What is t

ella [17]

Answer:

Part a)

$t = 5.1 s$

Part b)

$x = 176.7 m$

Explanation:

Initial speed of the launch is given as

$v_i = 40 m/s$

angle = 30 degree

Now the two components of the velocity

$v_x = v_i cos30$

$v_x = 34.6 m/s$

similarly we have

$v_y = v_i sin30$

$v_y = 20 m/s$

Part a)

Now to find the time of flight we will have

$\Delta y = v_y t + \frac{1}{2}at^2$

$-25 = 20 t -\frac{1}{2}(9.81)t^2$

$t = 5.1 s$

Part b)

Distance at which the ball will land is given as

$x = v_x t$

$x = 34.6 (5.1)$

$x = 176.7 m$

Part c)

Since x direction there is no acceleration so it will move with uniform speed while in y direction it will accelerate due to gravity

A cylindrical tank has a tight-fitting piston that allows the volume of the tank to be changed. The tank originally contains 0.1

Shkiper50 [21]

Answer:

0.10013 atm

Explanation:

Applying Boyle's Law,

P'V' = PV................... Equation 1

Where P' = Initial pressure of air, V' = Initial volume of air, P = Final pressure of air, V = Final volume of air.

make P the subject of the equation

P = P'V'/V..................... Equation 2

Given: P' = 0.355 atm, V' 0.110 m³, V = 0.390 m³

Substitute into equation 2

P = 0.355(0.11)/0.39

P = 0.10013 atm.

For your senior project, you would like to build a cyclotron that will accelerate protons to 10% of the speed of light. The larg

viva [34]

Answer:

The magnetic field is 1.16 T.

Explanation:

speed, v = 10% of speed of light = 3 x 10^7 m/s

diameter, d = 54 cm

radius, r = 0.27 m

charge, q = 1.6 x 10^-19 C

mass, m = 1.67 x 10^-27 kg

Let the magnetic field is B.

The centripetal force is balanced by the magnetic force.

$qvB=\frac{mv^2}{r}\\\\B =\frac{mv}{qr}\\\\B =\frac{1.67\times 10^{-27}\times 3\times 10^{7}}{1.6\times 10^{-19}\times 0.27}\\\\B =1.16 T$
