An object moving with a speed of 48 m/s has a kinetic energy of 4,632 J, what is the mass, in kg, of the object?
Please note the following:
Use g= 9.8 m/s2 for gravity
• Do not use commas in your answer to show place value.
• Do not use units in your answer.
As you work, please round to the nearest hundredth.
• Round your final answer to the nearest tenth if necessary. Plz help it’s a quiz

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
