A ball whose mass is 1.3 kg is suspended from a spring whose stiffness is 3 N/m. The ball oscillates up and down with an amplitude of 10 cm.
(a) What is the angular frequency?
(b) What is the frequency?
(c) What is the period?
(d) Suppose this apparatus were taken to the Moon, where the strength of the gravitational field is only 1/6 of that on Earth. What would the period be on the Moon? (Consider carefully how the period depends on properties of the system; look at the equation.)
A projectile is launched at an angle of 60o with respect to the horizontal from the edge of a cliff which is 100 m high. Its initial speed is 30 m/s. find the displacement vector for the motion of the projectile
A rocket is fired at a speed of 75.0 m/s from ground level, at an angle of 60.0 degrees above the horizontal. The rocket is fired toward the ground 11.0-m high wall, which is located 27.0 m away. By how much does the rocket clear the top of the wa..
