The position of a mving point in space is `x=2t, y4t, z=4t` where t is measured in seconds and coordinates of moving point are in kilometers: The distance of thepoint from the starting point `O(0,0,0) in 15 sec is (A) 3 km (B) 60km (C) 90km (D) 120km

The equations of motion of a rocket are x=2t,y=-4t and z=4t, where time t is given in seconds,and the coordinates of a moving points in kilometers.What is the path of the rocket? At what distance will be the rocket from the starting point O(0,0,0) in 10s?

The equation of motion of rockets are x=2t, y=-4t, z=4t where the time 't' is given in second and the coordinate of a moving point in kilometres. What is the path of the rockets? At what distance will the rocket be from the starting point O(0, 0, 0) in 10s.

The equation of motion of a missile are x = 3t, y = -4t, z = t, where the time ‘t’ is given in seconds, and the distance is measured in kilometres. Based on the above answer the following: At what distance will the rocket be from the starting point (0, 0, 0) in 5 seconds?

A man travels 3 km in the East and turns to South and moves 4 km. How far is he from the starting point ?

A starts walking from a point P. A goes westward and covers a distance of 4 km and then turns to his right and walks 3 km. How far A is from the starting point?

A man starts from a point and moves 3 km North, then turns to West and goes 2 km. He turns North and walks 1 km and then moves 5 km towards East. How far is he from the starting point?

Study the information given below carefully and answer the questions that follow : From a same point K , Indu and Soumya walked in opposite directions. After walking 5 km, Indu turned right and walked 3 kms, again turned right and walked 5 kms. From the starting point Soumya walked 4 km and turned left. How far is Indu from the starting point ? 1) 1 km 2) 2 km 3) 3 km 4) 4 km 5) 5 km

The positions corrdinate of particle that is confined to move along a straight line is given by x = 2t^(2) -24t +6 where x is measured form a convenient origin and t is in second. Determine the distance travelled by the particle during the interval from t = 1sec to t = 4sec .

A man travels 12 km west, then 3 km towards south and then 8 km towards east. How far is he from the starting point? 1) 23 km 2) 20 km 3) 15 4) 5 km 5) none of these
