When the man pushes downward on the box at an angle of 30, determine the maximum mass of the box he can move?
A golfer, driving a golf ball off the tee, provides the ball a velocity of +39 m/s. The mass of the ball is 0.045 kg, and the period of the impact with the golf club is 3.95 x 10^-3 s. (i) Determine the change in the momentum of ball
Avoid the weight of the ball, as it is so much less than the force of the bat. Select the direction of the incoming ball as the positive direction.
Calculate the rate constant of a first-order reaction which has 7.70 minutes for the reactant concentration to drop to half of its initial value?
A jogger of 85 kg is heading due to east at a speed of 2.5 m/s. A jogger of 55 kg is heading 30° north of east at a speed of 3.9 m/s. Determine the magnitude and direction of the sum of momentum of the two joggers.
Explain how long will reaction take for1/8 the reactant concentration to drop the initial value of reactions because some certain have the first-order reaction which is having a rate constant of 2.60×10-3 s-1.
