The mass of the reciprocating parts is 250 kg. When the crank has travelled 60° from I.D.C, the difference between the driving and the back pressures is 5. During a trial on steam engine, it is found that the acceleration of the piston is 36 m/s2 when the crank has moved 30° from the inner dead...Mass Acceleration, calculate the net force on the obiect. 9 kg F = mea = 12 kg F mea = a 3 m/s a 4 m/s 5 kg F = mea = 200 kg a = 40 m/s 200 Al a = 6 m/s ) 200 10) Challenge: A student is pushing a 50 kg cart, with a force of 600 N. Another student measures the speed of the cart, and finds that the cart is only accelerating at 3 m/s .
string to a 19 kg mass which hangs over the top edge of the ramp. Assuming that frictional forces may be neglected, what is the magnitude of the acceleration of the 19 kg block? A)3.8 m/s2 B)4.5 m/s2 C)4.2 m/s2 D)4.0 m/s2 4) T-m1gsin(theta) = m1*a; m2g-T = m2a; solve for a and use given values 5)A 0.140 kg baseball is thrown with a velocity of ... A helicopter of mass 1000 kg rises with a vertical acceleration of 15 m s–2. The crew and the passengers weigh 300 kg. Give the magnitude and direction of the (a) force on the floor by the crew and passengers, (b) action of the rotor of the helicopter on the surrounding air, (c) force on the helicopter due to the surrounding air.
