A body is projected horizontally from the top of a tower of height 4.9m with a velocity of 9.8m/s. The velocity with which the body strikes the ground is? View Solution STATEMENT-1: A particle si projected at an angleθ(<90)to horizontal, with a velcotiyu. When particle strikes the ...
The escape velocity is derived from this energy balance. 4. Independence from Angle: The escape velocity Ve is independent of the angle of projection. Whether the body is thrown vertically upwards or at an angle θ, the required speed to escape remains the same. The angle only affects the...
Question: If an object travels half its total path in the last second of it's fall from rest, how high was it initially? Second Kinematic Equation: The second kinematic equation is a relation between initial velocity(u), acceleration(a), covered dist...

The body is thrown at a speed of three times the escape speed: Vi=3Ve 3.Conservation of Mechanical Energy: In the absence of external forces, the mechanical energy is conserved. The total mechanical energy at the Earth's surface (initial) is equal to the total mechanical energy in interste...
A rocket is launched vertically upward, from Earth's surface, at a speed of 4.5km/s. What is its maximum altitude? A body is projected vertically upwards from the surface of the earth with a velocity equal to \frac{3}{4} escape ve...
