When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). the racquet exerts a force of 540 n on the ball for 5.00 ms, giving it a final velocity of 45.0 m/s. using these data, find the mass (in grams) of the ball.

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that decays in a nuclear transmutation 3. parent element the change of one chemical element into another by nuclear decay or radioactive bombardment 4. transmutation the time required for the decay of one-half of the atoms in a sample of radioactive material

What is "decrease in velocity" i need offering 60 !

The momentum of a man riding his bicycle downhill can be calculated. the bicycle and the man have a combined mass of 40 kg. the velocity of the bicycle is 10 m/s. calculate the momentum.
