A 15-N force and a 45-N force act on an object in opposite directions

Physics
1 answer:
lidiya [134]2 years ago
8 0

Answer:

30-N

Explanation:

Because they are both acting on an object going opposite directions, then you simply subtract the 15 from 45 as 45N of force is stronger than 15N of force.

o-na [289]

Answer:

Vf = 14.7 m/s

Explanation:

Vf² = Vi² + 2 * a * Δy

given:

a = 9.81 m/s²

Δy = 11m

Vi = 0 when upon release

Vf² = 0 + 2 (9.81) 11

Vf = 14.7 m/s

Encuentre en km.h la velocidad de un tigre que corre 550 km.h en 69min​
Len [333]

Answer:

v = 478.26 km/h

Explanation:

The question is "find in km.h the speed of a tiger that runs 550 km in 69min"

Distance, d = 550 km

Time, t = 69 min = 1.15 h

We need to find the speed of the tiger. The speed of an object is equal to the total distance covered divided by time taken. So,

v=\dfrac{550\ km}{1.15\ h}\\\\v=478.26\ km/h

So, the speed of the tiger is 478.26 km/h.
