Arocket travels vertically at a speed of 1300 km/hr.1300 km/hr. the rocket is tracked through a telescope by an observer located 13 km13 km from the launching pad. find the rate at which the angle between the telescope and the ground is increasing 3 min3 min after the lift-off.

0

Explanation:

Given:

initial velocity,

distance of telescope from the launch pad,

time after which the observation starts, t = 3 min.

Now, from the equation of  motion:

Which indicates that the after the given time the rocket would have fallen down on the ground if it did not had an acceleration of its own.

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
