2. There is a bell at the top of atower thatis 50m high. The bell weights 190 NThe bell hasenergy. Calculate it
Answer (1)
Answer:9500J-To calculate the potential energy (E\underline {}p)E p) of the bell, we use the formula:E\underline {}p = mg * hE p=mg∗hwhere mm is the mass of the bell, gg is the acceleration due to gravity, and hh is the height of the bellGiven:m = 190 Nm=190N (the weight of the bell),g = 9.8 m/s^{2}g=9.8m/s 2 (acceleration due to gravity),h = 50 mh=50m (height of the bell)1Convert the weight of the bell to mass by dividing by gg:m = 190 Nm=190Nm = 190 N / 9.8 m/s^{2}m=190N/9.8m/s 2 m = 19.3181818... kgm=19.3181818...kg2Calculate the potential energy:E\underline {}p = m * g * hE p=m∗g∗hE\underline {}p = 19.3181818... kg * 9.8 m/s^{2} * 50 mE p=19.3181818...kg∗9.8m/s 2 ∗50mE\underline {}p = 9500 JE p=9500J
