(a) Explanation The player start to chase his opponent at t = 0 s . Write the equation to find the position of opponent at this moment. d op = v v i , opponent t 1 Here, d op is the distance between opponent and player at t = 0 s , v i , opponent is the velocity of opponent at t = 0 s , and t 1 is the time after t = 0 s which player decided to chase the opponent. Write the Newton’s equation of motion to find the displacement of player at any instant t > 0 . Δ x player = v i , player t + 1 2 a player t 2 (I) Here, Δ x player is the displacement of player, v i , player is the initial velocity of player, t is the time and a player is the acceleration of player. Write the Newton’s equation of motion to find the displacement of opponent at any instant t > 0 . Δ x opponent = v i , opponent t + 1 2 a opponent t 2 (II) Here, Δ x opponent is the displacement of opponent and a opponent is the acceleration of opponent. Write the relation between Δ x player and Δ x opponent when the players are side by side. v i , player t + 1 2 a player t 2 = Δ x opponent + 36.0 m . Rewrite the above equation by substituting equations (I) and (II). Δ x player = Δ x opponent + 36.0 m (III) Conclusion: Substitute 12.0 m/s for v i , opponent and 3 (a) To determine The distance travelled by player to catch the opponent.

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, fo…

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12.6 m/s, skates by with the puck. After 3.4 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.2 m/s?, how long does it take him to catch his opponent?

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 2.00 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.44 m/S?, howlong does it take him to catch his opponent? (a) How long does it take him to catch his opponent?(Assume the player with the puck remains in motion at constant speed.)(b) How far has he traveled in that time?

A pedestrian is running at his maximum speed of 6.0 m/s to catch a bus stopped at a trafficlight. When he is 15 m from the bus, the light changes and the bus accelerates uniformly at 1.00m/s2. Does he make it to the bus? If so, how far does he have to run in order to catch it? If not,how close does he get?
