Answer:
The answer is
<h2>4260 N</h2>
Step-by-step explanation:
The force acting on an object when given the mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 142 kg
acceleration = 30 m/s²
So we have
Force = 142 × 30
We have the final answer as
<h3>4260 N</h3>

D since (-5 x -5) = 25 and (7 x -8) = -56. Add 25 and -56 and your answer is D. -31
Answer:
<h3>1 secs</h3>
Step-by-step explanation:
Given the height of the discus can be modeled by the equation y=−16x
^2
+32x+4, where y represents the height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.
Velocity v = dy/dx = 0
dy/dx = -32x + 32
0 = -32x + 32
32x = 32
x = 1 secs
Hence it will take the discus 1 secs to reach its maximum height
