An object is projected upwards with a velocity of 100m/s . it will strike the ground after (aproximatelu)
Answers
according to the given question,
⇒ u = 100 m/s
⇒ v = 0 m/s
⇒ g = - 10 m/s²
we should find the approximate time taken to reach the ground
so , we know that ,
v = u - gt
implies ,
t = v - u / -g
t = 0 - 100 / - 10
t = 10 seconds .
therefore the approximate time taken to reach the ground is 10 s + 10s = 20s seconds.

Answer:
The correct answer is 20 sec
Explanation:
According to the given question,
⇒ u = 100 m/s
⇒ v = 0 m/s
⇒ g = - 10 m/s²
we should find the approximate time taken to reach the ground
so , we know that ,
v = u - gt
implies ,
t = v - u / -g
t = 0 - 100 / - 10
t = 10 seconds .
therefore the approximate time taken to reach the ground is 10 s + 10s = 20s seconds.
velocity is the directional speed of a object in motion as an indication of its rate of trade in function as determined from a selected body of reference and as measured by a specific fashionable of time (e.g. 60 km/h northbound).[1] speed is a essential concept in kinematics, the department of classical mechanics that describes the motion of our bodies.
pace is a physical vector quantity; each significance and path are needed to define it. The scalar absolute value (importance) of velocity is referred to as velocity, being a coherent derived unit whose amount is measured inside the SI (metric device) as metres consistent with 2nd (m/s or m⋅s−1). for instance, "five metres according to 2d" is a scalar, while "five metres in line with 2d east" is a vector. If there's a exchange in velocity, direction or both, then the object is said to be undergoing an acceleration.
