Answer:
2.74 N-s
Explanation:
m = mass of the basketball thrown towards the floor = 0.60 kg
v₀ = initial speed of the ball before hitting the floor = 5.4 m/s
θ = angle made by the direction of motion of the ball with the vertical before and after the collision = 65°
I = Impulse delivered to it by the floor
Impulse delivered to the ball by the floor is given as
I = 2 m v₀ Cosθ
Inserting the values
I = 2 (0.60) (5.4) Cos65
I = 2.74 N-s
Answer:
(472i + 80.3j) m
Explanation:
Given the following :
Distance of tee shot = 300m
Distance of second shot = 189.0 m
Displacement r1 of tee shot :
r1 = 300 mi
Displacement r2 of second shot :
r2 = 172.0 mi + 80.3 mj
The final displacement of the golf ball from the tee:
r_final = r1 + r2
r_final = (300i)m + (172.0i + 80.3j) m
r_final = (300 + 172)i m + 80.3j m
r_final = (472i + 80.3j) m
Both, there are two different types of molecules to distinguish that
Answer:
IN MOTION
Explanation:
An apparent change in the frequency of waves, as of sound or light, occurring when the source and observer are in motion relative to each other, with the frequency increasing when the source and observer approach each other and decreasing when they move apart.
