A 44 kg child jumps off a 2.2 kg skateboard that was moving at 8.0 m/s. The skateboard comes to a stop as a result. Find the spe

Furkat [3]

Answer:

$v_f=8.4m/s$

Explanation:

We need to use the conservation of momentum Law, the total momentum is the same before and after the kid leaves the skate.

In the axis X:

$(m_{kid}+m_{skate})*v_{o}=m_{kid}*v_f$ (1)

$v_f=(m_{kid}+m_{skate})*v_{o}/m_{kid}=(44+2.2)*8/44=8.4m/s$

how you could calculate a time step (dt) if you have a vector of accumulative distance (ie the distance keeps adding every step)

lakkis [162]

Answer:

dt = ds/dv.

Explanation:

to calculate the time step if you have a vector of accumulative distance and instanteneous velocity vector can be expressed bellow

solution

ds = dv/dt

divide the step distance by the instantaneous velocity you will get the time step.

that it

dt = ds/dv.

so to calculate the time step having a vector that keeps adding every step and speed at that moment is this dt = ds/dv.
