A van moves with velocity of 36 km/hour. then it is accelerated with acceleration of 2 m/s². calculate : a) velocity, b) distance traveied in 10 second after the van being accelerated
1. A van moves with velocity of 36 km/hour. then it is accelerated with acceleration of 2 m/s². calculate : a) velocity, b) distance traveied in 10 second after the van being accelerated
a) s = 25 m = 0,025 km , t = 5 s = 5/3600 jam , v = 36 km/jam
b) s = 200 m = 0,2 km , t = 10 s = 10/3600 jam , v = 30 m/s^2 = 108 KM/jam
2. A student conducts an experiment to determine the acceleration of a trolley He measures the velocity of the trolley. At one instant , the velocity if the trolley is 1.0 m/s. Two seconds later, the velocity is 5.0 m/s. What is the acceleration of the trolley?

5. The ends of a tuning fork oscillate at a frequency of 440 Hz with an amplitude of 0.50 mm. Determine (a) the maximum velocity and (b) the maximum acceleration of the ends.
(a) The maximum velocity of the ends can be determined using the equation:
v_max = A * ω
where A is the amplitude and ω is the angular frequency given by
ω = 2πf
Substituting the given values, we have:
v_max = 0.5 mm * (2π * 440 Hz) = 2828 mm/s
(b) The maximum acceleration of the ends can be determined using the equation:
a_max = ω^2 * A
Substituting the given values, we have:
a_max = (2π * 440 Hz)^2 * 0.5 mm = 3.12 x 10^7 mm/s^2
Note: The units for velocity and acceleration should be consistent, in this case mm/s and mm/s^2 respectively

9. A roller coaster's velocity at the top of a hill is 10 m/s. Two seconds later it reaches the bottom of the hill with a velocity of 26 m/s. What was the acceleration of the coaster?
Jawaban:
a = 8m/s²
Penjelasan dengan langkah-langkah:
Vo= 10m/s
V = 26m/s
t = 2 s
a = ?
a= V - Vo / t
= 26 - 10 / 2
= 16 / 2
= 8 m/s²
