Answer:
36.74 N
Explanation:
Given that:
A crate of oranges with a total mass (m) = 6.7 kg
angle θ = 0.7 rad
angle θ = 
angle θ = 40°
acceleration = 4.2 m/s²
Given that:
T cosθ = ma
T cos 40° = 6.7 × 4.2
T = 
T = 
T = 36.74 N
Thus, the tension in the rope = 36.74 N
Answer:
Explanation:
7.0 - 4.0 = 3.0 kg water
3.0 kg(2.26 x 10⁶ J/kg = 6.78 x 10⁶ J
220 V(15 A) = 3300 W
1 W = 1 J/s
6.78 x 10⁶ J / 3300 J/s = 2054 s
2054 s / 60 s/min = 34 min
After the foot leaves the ball, the acceleration is always downward and is equal to g at all points
Answer:
E)
Explanation:
Because of Newton's Second Law, which says any action will be opposed by a reaction of the same magnitude, then no matter what, no matter if the box does or does not move, the bat bouces back, or what happens after the hit, when hitting the box the force ithbox exerts on the bat is exactly 1500 N.
