It is described as the rate of change of velocity of an object with respect to time. It is a vector quantity. Also, if there is a change in the velocity of the object, then the object is said to …

Q. Calculate the recoil velocity of a carbine whose mass is 10 kilograms and it shoots a bullet weighing 0.500 grams. The velocity of the shell is 600 m/s. A. Given- mass of carbine M =10 …

Δv is the change in its velocity. Further, Δ v = v f – v i . Where . v f is the final velocity and v i is the initial velocity. Substituting for Δv in Equation 1, we get: q V = 1 2 m (v f – v i) ². This …

Given that. du du ax = +u-+v. +w du du ôt əx ду əz V = 3tî +xzj+t Find the magnitude of velocity and acceleration at point (1,1,1) at time t = 1 second. Write the acceleration vector. If the fluid …

Find a formula for the velocity at any time (in terms of k ): v(t) = (Ce-((k/4)(t)) -39.2)/k Find the limit of this velocity for a fixed time to as the air resistance coefficient k goes to 0. (Write to as to in …

See the illustration below. The formula m + M V = (2gh)!/2 gives the velocity (in ft/sec) of a bullet with weight m fired into a block with weight M, that raises the height of the block h feet after …

The units for acceleration are meters per second per second or m/s. (Final velocity -intial velocity) Acceleration = time a = The acceleration formula can be rearranged to solve for other …

P1.55. Find an algebraic formula for the steady velocity U of the block if it slides on an oil film of thickness h and viscosity μ . The block bottom area A is in contact with the oil. Neglect the …

Determine a formula for its velocity as a function of time assuming a resistive force F = −bv as well as gravity for two cases: ( a ) v → 0 is downward and ( b ) v → 0 is upward. (II) An object …
