Answer:
18.73 m/s^2
Explanation:
f = 2662 rpm = 2662 / 60 rps
r = 6.725 cm = 0.06725 m
Acceleration, a = r w
a = r x 2 x pi x F
a = 0.06725 × 2 × 3.14 × 2662 / 60
a = 18.73 m/s^2
Answer:
Frequency doubles.
Explanation:
Frequency doubles because Wavelength and Frequency are inversely proportional. That means if one decreases the other one increases. So, if wavelength is half, frequency is the opposite, doubles.
Answer:
Acceleration=4m/s²
Force applied =619.8N
Explanation:
Using equation of motion
V=u+at we have: u=o, v=50m/s
50= 0 + a×0.0121
a = 50/0.0121
a= 4m/s²
Neglecting resistance forces
F= ma, where a = v-u/t
F=m×(v-u)/t
F= 0.150 ×(50-0)/0.0121
F=7.5/0.0121
F= 619.8N
Answer:
F=30N
a= 3m/s^2
m=?
F=ma
30=m(3)
30/3=m
m=10kg
The mass of the ball is 10kg
