Physics questions (Example)

1.A net force F is required to give an object with mass m an acceleration of 11 m/s2. If a net force 27F is applied to an object with mass 3m what is the acceleration on this object? Please round your answer to the nearest whole number (integer). From Newton’s Second Law M1a1=M2a2 Thus from here we have M1=m a1=11m/s M2= 3m a2=? a2 =M1a1M2 = 11m3m = 3.6667 Acceleration on the object = 4m/s 2.Two point masses m and M are separated by a distance d. If the distance between the masses is decreased to one-third (1/3) d how does the gravitational force between them change? The force will be nine times as great the force will be one-third as great it is impossible to determine without knowing the numerical values of m M and d the force will be three times as great? Under the Universal Gravity the average speed is v = (v0 + vf)/2 = (0 + 40 m/s)/2 = 20 m/s So F = 4322 W/20 m/s = 138.06 N = 216.1 N 216N 11.A 6 x 105 kg space probe is traveling at speed v0 through deep space. Retrorockets are fired to slow down the probe and they generate a negative force of - 8 x 106 N over a distance of 3 x 106 m. The final speed of the probe is found to be 2803 m/s. Calculate the (initial) speed vo. Please round your answer to the nearest whole number (integer). m = 6 x 105 kg u = v0 m/s F = -8x106 N s = 3x 106 m F = ma a = F/m = -3x 106 /6 x 105 = -5 m/s^2 v2 = u2 + 2as v2 = (v0)2 + 2(-5)( 3x 106) v = (-3x106)v02 [...]
