en una superficie horizontal descansa un baúl de 100 n de peso para que esté comienza a moverse se necesita una fuerza horizontal de 20 n después de la que se inicia el movimiento basta una fuerza de 12 n para que el baúl siga moviéndose con una velocidad constante calcule los coeficientes de fricción estática y cinética debido a la interacción entre la superficie y el baúl

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
