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>

Answer:
40°
Step-by-step explanation:
Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.
