Answer:

-1.11 m/s²

Explanation:

v = at + v₀

Given v = 20 m/s, v₀ = 120 m/s, and t = 1.5 min = 90 s:

20 m/s = a (90 s) + 120 m/s

a = -1.11 m/s²

Answer:

-1.11 m/s²

Explanation:

A 150 kg object takes 1.5 minutes to travel a 2,500 meter straight path. It begins the trip traveling 120 m/s and decelerates to a velocity of 20 m/s. Its  acceleration was -1.11 m/s².

If an object moving at 12 m/s has a kinetic energy of 72 j what is the mass
EleoNora [17]
Simply, apply the formula E = \frac{1}{2}mv^{2} and insert the values of m = mass, v = velocity and E = Energy.
The result will be 72J =  \frac{1}{2}m(12m/s)^{2}, m = 1 kg

A complete series circuit consists of a 12.0 V battery, a 4.70 O resistor, and a switch. The internal resistance of the battery
RoseWind [281]

With the switch open, there's no current in the circuit, and therefore
no voltage drop across any of the dissipative elements (the resistor
or the battery's internal impedance).  So the entire battery voltage
appears across the switch, and the voltmeter reads 12.0V .

How do the principles of convection, conduction, and radiation explain how the water in the saucepan gets hot?
RSB [31]
<span>Heat comes from stove flame to the sauce pan by radiation through infrared energy, heat conducts the metal of the sauce pan; Convection brings cool water to the hot surface at the bottom of the hot sauce pan until all or most of the water is hot enough to boil.</span>
