Answer:
Driver hits the dog
Explanation:
From kinematics equation
and making a the subject
F=ma=800*-4=-3200 N
The driver is required to apply a force of 3200 N to effectively not hit the dog. However, when the driver applies 2000 N, this is less the required force by 1200 N hence the driver hits the dog.
A kangaroo will stay 0.699s in the air when he jumps.
<h3>What motion does the projectile make?</h3>A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A projectile is an object that is launched into the air horizontally and moves regardless of gravity.
<h3>How do you determine the rate of descent?</h3>G = -9.81 m/s2 is the acceleration of gravity close to the earth. Simply multiply the acceleration of gravity by the period since the object was released to determine the object's speed (or velocity). In other words, velocity is equal to -9.81 m/s2 * time, or V = gt.
<h3>According to the given information:</h3>From the conversion of energy =
t = √(2h/g)
= √((2 x 2.40) / 9.8)
=0.699 s
A kangaroo will stay 0.699s in the air when he jumps.
