Step 1
In this case, the object weighs 7 newtons, so the mass can be calculated using the formula weight = mass * gravity, where gravity is approximately 9.8 m/s^2. Therefore, the mass of the object is 7 / 9.8 = 0.714 kg. Show more…

An object travels in a circular path of radius $5.0$ meters at a uniform speed of 10 . meters per second. What is the magnitude of the object's centripetal acceleration? (A) $10.0 \mathrm{~m} / \mathrm{s}^{2}$ (B) $2.0 \mathrm{~m} / \mathrm{s}^{2}$ (C) $5.0 \mathrm{~m} / \mathrm{s}^{2}$ (D) $20 . \mathrm{m} / \mathrm{s}^{2}$
A particle is performing uniformly accelerated circular motion along a circle of radius $8 \mathrm{~m}$. It moves from point $\mathrm{A}$ to point $\mathrm{B}$ in time $0.5 \mathrm{~s}$. Its acceleration at $\mathrm{B}$ is $\left(\operatorname{in} m \mathrm{~s}^{-2}\right)$ (a) 10 (b) 8 (c) 6 (d) 2
