The horizontal component of the velocity of the ball is calculated by multiplying the speed by the cosine of the given angle.
x-component of speed = (31 m/s)(cos 35°)
= 25.39 m/s
Thus, the horizontal velocity component of the ball is 25.39 m/s.
Answer:
HII CAN I HAVE BRAINLIST PLEASE I NEED ONE MORE
Explanation:
Answer:
Speed only defines the magnitude of how fast an object is moving from one point to another. This is a scalar quantity (Only Value)
Velocity defines both how fast an object is moving and also in what direction the object is moving. This is a vector quantity (Value + Direction)
Answer:
q₁ = q₂ = Q = 14.8 pC
Explanation:
Given that
q₁ = q₂ = Q = ?
Distance between charges = r =7.3 cm = 0.073 m
Combined electric field = E₁ + E₂ = E = 50 N/C
Using formula
Rearranging for Q
This is an example of Uniform Speed
EXPLANATION
Uniform Speed => no change in speed
Uniform Accelerations Speed => There is a change in speed, but the acceleration remains the same.
