Answer:
a. Potencia = 250 Watts
b. Tiempo = 333.33 segundos
Explanation:
Dados los siguientes datos;
Energía = 5000 Joules
Tiempo = 20 segundos.
Para encontrar el poder;
Poder = energía/tiempo
Potencia = 5000/20
Potencia = 250 Watts
B. ¿Para saber cuánto tarda una máquina en realizar el mismo trabajo;
Dado: potencia = 15 W
Tiempo = energía/poder
Tiempo = 5000/15
Tiempo = 333.33 segundos
Explanation:
we know
v=u-gt
At max height v=0
uy=usin30
now,25sin37=gt
15.07/9.8=t
t=1.53s to reach max height now to come on ground it takes same time
so time taken t=3.07s
We know ,range=ucos37×t
=25cos37×3.07
max distance=61.3meter
Answer:
the triangle is a mathematical symbol which denotes change in a quantity . it is called delta. so delta v= final velocity -initial velocity,delta t=time during the final velocity - time during the initial velocity was recorded.
Explanation:
Yes it can . .............
