CBSE Class 11-science - Acceleration Videos

• a bullet travelling with speed of 16m/s penetrates a tree trank come to rest in 0.4m find the time taken during retard
• the angle of inclination of an inclined plane is 60 degrees. Cooefificent of friction between 10kg body on it and it's surface is 0.2,g= 10ms secnod squre. The acceleration of the body in meter ler second is
• If acceleration= X². Find velocity when x=2m. Given at x=0 when body is at rest  
• A particle travels in a straight line, such that for a short time 2s≤t≤6s, its motion is described by v=(4/a) m/s, where a is in m/s 2 . If v =8m/s when t = 2s, determine the particle's acceleration when t = 4s.
• please solutions
  
• Distance covered by a train is 72 km with initial velocity of 20 m/s in 30 minutes. Find it's acceleration
• Derive an expression for average acceleration and instantaneous accelerationfor the motion of an object in x-y plane
• Velocity as a function of position for a particle is given as v = √x (ii) Find acceleration as function of time.?
• Formula to find distance travelled by an uniformly accelerated body is
• The distance x covered by a body moving in a straight line in time t is given by the relation- 2x²+3x=t If v is the velocity of body at a certain instance of time, find it's acceleration.
