a)Describe the motion of an object in which it speed is constant what the velocity is changing ? b)Can the average speed ever be zero? Explain? c)Explain the condition of the velocities of the two bodies in motion when: i)there velocity are added for relative velocity ii)there velocity are subtracted for relative velocity d)What is indicated by the statement" acceleration of a body is 10m/s²? e)Describe the conditions when the acceleration of a body is positive,negative and zero? f)what is the value of acceleration in the following conditions? i)When a body thrown upwards in maximum height ii)When a body comes as it initial position after motion iii)When a body gains a velocity of 60 m/s within 5 second from the rest position iv)When a body moves with constant velocity v)When a body falling downwards strike the ground g)Which formula will you use to calculate relative velocity of a body in the following conditions? i)If two boys are running in the same directions from the same references point ii)If two girls are running in opposite directions from the same reference point
