Akangaroo jumps straight up with an initial vertical velocity of 2.4\,\dfrac{\text{m}}{\text{s}}2.4 sm 2, point, 4, space, start fraction, m, divided by, s, end fraction. we want to find the maximum height of the jump.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Give one example to show that when substances are mixed, it may result in a chemical or a physical change depending on the conditions.

An athlete performing a long jump leaves the ground at a 27.0 degree angle and lands 7.80m away. what was the takeoff speed?
