Use the figure to help you find the weight (Fg) of the body if the tension in both wires is 3.7 newtons.
please help me A person launches a home-built model rocket straight upinto the air at y = 0 from rest at time t = 0 . (The positive y-direction is upwards). The fuel burns out at t = t0. The position of the rocket is given by with a0 and g are positive. Find the y-components of the velocity and acceleration of the rocket as a function of time. Graph ay vs t for 0 < t < t0.
HELP Acceleration is defined as the rate of change for which of the following? A. time B. velocity C. position D. displacement Please explain as well :D

A bowling ball with a mass of 4.5 kg travels at a velocity of 37 m/s for 2.5 s until it is stopped at the end of the lane by the ball return. What additional information is required to determine the weight of the bowling ball? A. the speed at which the ball return captured the ball B. the amount of friction from the bowling lane acting on the bowling ball C. the acceleration due to gravity acting on the bowling ball D. the force the bowler applied to the bowling ball
A polo player hits a ball with a mass of 0.42 kg with a force of 7.35 Newtons. How does the force the polo player's mallet exerted on the ball compare to the force the ball exerted on the mallet? A. The force of the on the mallet is less in magnitude and opposite in direction to the force the ball exerted on the mallet. B. The force of the mallet on the ball is greater in magnitude and opposite in direction to the force the ball exerted on the mallet. C. The force of the mallet on the ball is equal in magnitude and opposite in direction to the force the ball exerted on the mallet. D. The force of the mallet on the ball is equal in magnitude and in the same direction to the force the ball exerted on the mallet.
