Question

Ayuda, doy corona :(

Answer 1

CALCULO Vf (VELOCIDAD FINAL), PARA BUSCAR D (DISTANCIA O ALTURA)

$\bold{v_f= v_0 + a \cdot t}$

$\bold{v_f=15.00m/s+ (10.00m/s^2)(4.00s)}}$

$\bold{v_f=15.00m/s+ (40.00m/s)}$

$\boxed{\bold{v_f = 55.00m/s} }$

AHORA CALCULO D (DISTANCIA O ALTURA)

$\bold{d = 0.5\cdot(v_f+v_0)\cdot t}$

$\bold{d = 0.5\cdot(55.00m/s+15m/s)\cdot(4.00s)}$

$\bold{d = 0.5\cdot(70.00m/\cancel{s})\cdot(4.00\cancel{s})}$

$\boxed{\bold{d = 140.00m} }$
