At what distance from the gun the bullet will strike the ground, if a bullet is fired with an initial velocity 250 ms–1 at an angle of 30º with the horizontal.
Answers
Answer:
5.4125 km
Explanation:
R = u²sin2∅ / g
where R = horizontal range
u = initial speed
∅ = angle with respect to horizontal
g = acceleration due to gravity
R = (250)²sin60/g
= 62500√3/2×10
= 5.4125 km
Answer:
The correct answer is 5.4125 km

u = initial speed
∅ = angle with respect to horizontal
g = acceleration due to gravity
R = (250)²sin60/g

Velocity is the directional speed of a item in movement as a demonstration of its fee of exchange in position as determined from a particular body of reference and as measured through a selected trendy of time (e.g. 60 km/h northbound).[1] pace is a fundamental idea in kinematics, the branch of classical mechanics that describes the motion of bodies.
pace is a physical vector amount; each importance and direction are had to outline it. The scalar absolute value (magnitude) of speed is called pace, being a coherent derived unit whose quantity is measured in the SI (metric machine) as metres in keeping with 2d (m/s or m⋅s−1). as an instance, "5 metres in step with 2nd" is a scalar, whereas "five metres in step with second east" is a vector. If there is a exchange in velocity, direction or both, then the object is stated to be present process an acceleration.
To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.
For example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration.
