Answer:
W = M g weight of ball
T cos θ = W balancing vertical forces
T sin θ = F balancing horizontal forces
tan θ = F / W dividing equations
F = W tan θ when θ equals zero F equals zero
Answer: x= 4.761 m/s
t=0.786 sec
Explanation: In a projectile motion (or 2D motion), the object is launched with an initial angle and an initial velocity
The components of the velocity are
<em>The magnitude, which is the speed, and the direction in which the motion is happening.</em>
Similarly the displacement has the components
The last formula is valid only if the object is launched at ground level, as our frog does.
There are two times where the value of y is zero, when t=0 (at launching time) and when it lands back from the air. We need to find that time t by making y=0
Dividing by t (assuming t different from zero)
Then we find the total flight as
Replacing this time in the formula of x
We can solve for
Knowing that x=2.20 m and °
We now compute t
Answer:
The deflection of the spring is 34.56 mm.
Explanation:
Given that,
Diameter = 10 mm
Number of turns = 10
Load = 200 N
We need to calculate the deflection
Using formula of deflection
Put the value into the formula
Hence, The deflection of the spring is 34.56 mm.
Two colliding objects will exert equal forces upon each other. If the objects have different masses, then these equal forces will produce different accelerations.
