The driver of a car moving at 30 m/s suddenly sees a truck that is moving in the same direction at 10 m/s and 60 m ahead. The maximum deceleration of the car is 5 m/s^2. a. Will the collision occur if the a second stone is dropped. Prove that the distance between the stones [...]

Divide a plane 10 m long and 5 m high into three parts so that a body starting from rest takes equal times to slide down these parts. Also find the time taken then. Divide a plane 10 m long and 5 m high into three parts so that a body starting from rest takes [...]

A stone falling from the top of a vertical tower has descended x meter when another is dropped from a point y metre, below the top. If they fall from rest and reach the ground together, show that the A stone falling from the top of a vertical tower has descended x meter when another [...]

A stone is let to fall from a balloon ascending with an acceleration f. After time t, a second stone is dropped. Prove that the distance between the stones after time t, since the second stone is dropped, a second stone is dropped. Prove that the distance between the stones after time t A stone [...]

A car starts from rest and moves with constant acceleration and covers the distance between two points 180 m apart in 6 s, Its speed as it passes the second point is 45 m/s Find a. Its acceleration A car starts from rest and moves with constant acceleration and covers the distance between two points [...]

A racing motor boat speeds up in a straight line in a lake, from rest. Referring to the acceleration displacement graph for the speeding boat, find its speed when it passes a raft at a distance of 40 m A racing motor boat speeds up in a straight line in a lake find its speed [...]

Referring to v – s diagram, find: a. Acceleration of the particle when its velocity becomes half of the initial velocity. b. Total distance covered by the particle find: a. Acceleration of the particle when its velocity becomes half of the initial velocity. b. Total distance covered by the particle Referring to v - s [...]

A rigid ball traveling in a straight line ( the x axis) hits a solid wall and suddenly rebounds during a brief instant. The vx -t graph in Fig. 4,130 shows this ball’s velocity as a function of time. During the first 20 s of its motion, find (a) its displacement 130 shows this ball's [...]

Two cars A and B, move along the x axis. Car A starts from rest with constant acceleration while car B moves with constant velocity. A. At what time (s) , t (s), if any, do A and B have the same position? do A and B have the same position? if any move along [...]
