A high diver leaves the end of a 5.0-m-high diving board and strikes the water 1.3 s later, 3.0 m beyond the edge of the board. Considering the diver as a particle (neglect her dimensions), determine the following quantities: Her initial velocity v0→ (both magnitude and direction, i. e. the angle θ with the horizontal).

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
