Answer:
30m/ s
Explanation:
this is an example of a projectile, where the path traced by the ball will be a downward parabola.
one must know that the <em>vertical velocity of an object having projectile motion is zero at the top of its trajectory</em> and that the <em>horizontal velocity remains constant throughout</em>.
this means, at the top of the trajectory the <u>ball's overall speed will be equal to its horizontal velocity</u>.
and horizontal velocity is given 30 m/s
hence, overall speed of the ball = 30m/ s
Answer:
Velocity= Distance divided by time divided by degree or direction.
Explanation:
Speed=DIstance divided by time
It's the volume of a cube with edges one meter in length.
Answer:
Explanation:
Density is defined as mass per unit volume.
Specific Gravity is the ratio of the density of a substance to the density of water, or it is the ratio of the weight of a body to the weight of an equal volume of water
Therefore we can compute the S to be
S = W / W-W1
W = weight of the solid in air = 0.8000N
W1 = weight of solid in water = 0.7295N
S = 0.8 / 0.8- 0.7295 =
0.8/ 0.0705 = 11.35
Density of the object = specific gravity × density of water
= 11.35 × 1 g/cm3 = 11.35 g/cm3
