50
It traveled for some time 'T', during which its speed was 'S'.S x T = 100, so T = 100/S(S + 15) x T = 130Substitute [ T = 100/S ]:(S + 15) x (100/S) = 130100 + 1500/S = 130100S + 1500 = 130S1500 = 30S50 = S==================================Check:At the original speed of 50, it took 2 hours to travel 100 miles.At (50 + 15) = 65, it would have went (2 x 65) = 130 miles.130 - 100 = 30 more miles yay!
u= 0 m/s v= 200 m/s m= 20 kg F= 100 N F= (mv - mu)/t 100 = (20*200 - 20*0)/t 100 = 4000/t t= 4000/100 t= 40 s hope it helps cheers ^_^
Use the Speed-Distance-Time formula. D=S x T T=D/S S=D/T Speed: 2 meters per second Distance: 100 meters. T=100/2 T= 50 seconds.
100 times a second, lightning strikes the Earth.
if you buy it there`s a 100% chance that it won`t.
From 1-10 how s-t-u-p-i-d this website is i give it a 100 >:)
t = s/v s = 15 km v = 100 km/h t = 15 km/(100 km/h) = 0,15 h = 9 minutes.
90kph but my T,S is 130kph

10kHz = 10,000 s^-1 This means that the wave makes 10,000 ( ten thousand ) cycles in 1 second. So 100 cycles is made in 100/10000 s 1/100 s or 0.01 s. NB remember k = kilo ( or one thousand) The S.I. unit for Hertz (Hz) is 'per second/ s^-1)
To determine the time for a body to acquire a velocity of 100 m/s under a constant force of 100 N, you can use the equation ( F = ma ). Rearranging it to solve for acceleration ( a = F/m ), the acceleration will be ( 100 N / 20 kg = 5 m/s^2 ). Then, using the equation ( v = at ), where ( v = 100 m/s ) and ( a = 5 m/s^2 ), you can solve for ( t ) (time), which becomes ( t = v/a = 100 m/s / 5 m/s^2 = 20 s ). Therefore, the force should act for 20 seconds.
