Answer:
a = 0.1067 [m/s²]
Explanation:
In order to solve this problem, we must first draw a free body diagram with the forces acting on it.
a)
In the attached image we can find the free body diagram.
b)
The net force can be found by performing a sum of forces on the X-axis, these forces are seen in the free body diagram.
∑Fx = Fr
where:
Fr = resultant force [N] (units of Newtons)
![F_{r}=275+275-310\\F_{r}=240[N]](https://tex.z-dn.net/?f=F_%7Br%7D%3D275%2B275-310%5C%5CF_%7Br%7D%3D240%5BN%5D)
c)
Acceleration can be found by means of Newton's second law, which tells us that the sum of the forces in a body or the resulting force is equal to the product of mass by acceleration.
∑F = m*a
where:
m = mass = 2250 [kg]
a = acceleration [m/s²]
![240=2250*a\\a=0.1067[m/s^{2} ]](https://tex.z-dn.net/?f=240%3D2250%2Aa%5C%5Ca%3D0.1067%5Bm%2Fs%5E%7B2%7D%20%5D)
Answer:
s = 307.34 m
Explanation:
In order to find the distance covered by the dragster during the given time, we will use second equation of motion. The second equation of motion is written as follows:
s = Vi t + (0.5)at²
where,
s = distance covered by the dragster = ?
Vi = Initial Velocity = 0 m/s
t = time interval = 3.97 s
a = acceleration = 39 m/s²
Therefore,
s = (0 m/s)(3.97 s) + (0.5)(39 m/s²)(3.97 s)²
<u>s = 307.34 m</u>
Answer:
b it is b part answer i think so
Ball is thrown at an angle of 20 degree with velocity 18 m/s
so first we will find the two components of the velocity


similarly for other component


now the ball will cover horizontal distance of 30 m till it reach to other player
so here we can use the formula of time




so it will take 1.77 s to reach the other player
