Answer:
Explanation:
From the question we are told that:
Period
Trial 1
Spring constant
Period
Mass
Trial 2
Period
Generally the equation for Spring Constant is mathematically given by
\mu=\frac{4 \pi^2 M}{T^2}
Since
Therefore
Answer:
W_net = 57.57J
Explanation:
We are given;
Mass of canister; m = 2kg
Initial velocity of the canister; v_i = 2.2 m/s
Final velocity of the canister; v_f = 7.9 m/s
From work energy theorem, the net work done is equal to the change in kinetic energy. Thus;
W_net = ΔKE
W_net = KE_f - KE_i
W_net = (1/2)mv_f² - (1/2)mv_i²
W_net = (1/2)m(v_f² - v_f²)
Plugging in the relevant values to give;
W_net = (1/2)(2)(7.9² - 2.2²)
W_net = 57.57J
The layers of a jawbreaker is all made of the same material. The layers of the Earth are not, it is made of different kinds of rock, magma, and metal is inside of the core
Answer:
Magnitude of the acceleration(g) = 9.7 meters/second²
Explanation:
Given:
Height of tower = 56 meter
Time taken = 3.4 second
Final velocity (v) = 33 meters/second
Initial velocity (u) = 0 meters/second
Find:
Magnitude of the acceleration(g)
Computation:
Using first equation of motion:
v = u + at
Magnitude of the acceleration(g)
v = u + gt
33 = 0 + g(3.4)
g = 33 / 3.4
g = 9.7 meters/second²
Magnitude of the acceleration(g) = 9.7 meters/second²
