let velocity of A be vvelocity of A wrt B = 4vtotal distance travelled by either trains=225mi.e velocity of A= 225/4*4 =14m/s (approx).i.e velocity of B = 42m/s
as soon as the stone is released...it becomes n object under free fall. Initial acceleration doesn’t matter. hence it is under an acceleration g i.e. 9.8 m/s 2 .
v = 18km/hr = 5m/s u=0 m/s t = 2 s a = ? According to equation of motion v = u + a.t 5 = 0 + a.2 a = 5/2 = 2.5 m/s 2
V P = 90 km/h = 25 m/s. V C = 72 km/h = 20 m/s. Time taken by the culprit to reach B from A= 10s Distance converted by culprit = v x t = 20 x 10 = 200 m. At time t = 10 sec the police jeep is 200 m...
acceleration due to gravity =g.Because as soon as the packet droped from ballon,it looses contact of balloon.It is under free fall now.There fore it occurs the acceleration due to gravity.
Just apply coordinate geometry. Path of projectile is parabola. I hope you know how to find it`s equation. You can also find the equation of straight line containing C whose slope is 3/4 and passes...
go and solve irodov book if you consider of having courage to do so.
time period will not change. take time period t = 2pi X (m/k)^1/2 for first case. then, take l/k = constant for the second case. put k eq in place of k in the formula. it comes out to be of same time...
A spring when connected by mass m gives time period T if spring is cut in n equal parts and each part connected in parallel with same mass. New time period will be
Radii of the log => r = root(A/pi) Time Period = 2pi*root(r/g) => 2pi*root(root(A/pi)/g) would be the final time period as the log would be lying on height of length h horizontally.
Because the body was initially at rest.So initial velocity u=0 so ut=0 so it has ommitted utTherefore s=1/2gt^2.The question is not given but i guess the question is of a body which is dropped from a...
It is falling down with constant velocity.So net force acting on it Is 0. Bouant force and it`s weight are equal
First we find the velocity by given dataAngle=15° ,Range=50 m, taking g=9.81 m/sR=Vo^2*sin2(angle)/g50=Vo^2*sin2(15)/9.8150=Vo^2*0.5/9.81 (since sin(30)= 0.5)490.5=Vo^2*0.5...
