If a footballer kicks a ball straight down the pitch at 6 ms-1 at an angle θ of 30° above the horizontal, what is the maximum height reached by the ball?

First we must remember our equations of motion, (SUVAT equations).S = Displacement U = Initial velocity V = Final velocity A = Acceleration T = TimeV = U + ATS = UT + (1/2)AT²

A circuit with a cell of voltage 6V and two resistors of resistance 6 Ohms each connected in parallel. What is the current through the Cell?

Step 1 - draw the circuit.
Step 2- Finding total resistance of resistors in parallel, 1/Rt = 1/R1 + 1/R2 where Rt is the total resistance of the circuit.
Step 3- Use Ohms laws...

Calculate the gravitational force acting on the Moon, caused by the Earth, given that the masses of the Earth and the Moon are 6 x10^24 and 7.3 x10^22, respectively. The distance between the Earth and the Moon is 384 400 km.

The relevant equation to use in solving this problem, from Newton's law of gravitation, is Force = ( universal constant of gravitation x mass of earth x mass of moon)/ (distance between earth and moon sq...

A photon of wavelength 656.3nm is emitted in the Balmer series of a Hydrogen emission lamp. (a). Show that the frequency of the photon is 4.57*10^14 Hz. (b).Use the Planck-Einstein relationship to calculate the energy of the photon.

(a). Firstly, pull out useful information . λ=656.3nm Secondly, identify relevant equation and rearrange to find frequency. λ=c/f => f=c/λ Calculate frequency using the given values (c=310^8 m/s), ...

A tall 2 meter tall basketball player shoots for the net that stands 3 meters from the ground. If he throws he ball from head height at an angle of 60 degrees and the ball travels at 10 meters per second, how far away is the hoop?
By taking the initial vertical speed as v_v = 6 sin(60) = 5.2 ms^-1.The max height of the ball is given by v_v² = u_v² + 2as. From this, s = 1...
