A projectile is fired with some velocity making certain angle with the horizontal. Which of the following graphs is the best representation for the kinetic energy of a projectile (KE) versus its horizontal displacement(x)? A particle of mass m slides on a frictionless surface ABCD starting from rest as shown in Figure. The part BCD [...]
A particle of mass m slides on a frictionless surface ABCD, starting from rest as shown in Figure. The part BCD is a circular arc. If it loses contact at point P, the maximum height attained by the particle from point C is : A particle of mass m slides on a frictionless surface ABCD [...]
