Four penguins are being pulled alone by a handler. THe masses of the three penguins and the tension in the two of the cords are M1 =14kg, m2=26kg, m4=23kg, T2=115N, and T4=320N. Find the acceleration of the system and b) the mass of m3 that is not give.
A block is pushed up a frictionless inclinded plane with initial speed V0 =5.50 m/s. The angle of incline is 0= 23.0ยบ. How far up the plane does the block go? How long does it take to get there?
