A force of 5 newton acts on a body of weight 9.80 newton. What is the acceleration produced in m/s2?
(A) 0.51
(B) 1.96
(C) 5.00
(D) 49.00
Answered Feb 05, 2023
Correct option is: (C) 5.00
Given, F = 5N
W = 9.80
a = ?
W = mg
\(9.80 = m \times 9.8\)
m = 1 kg
F = ma
\(5 = 1 \times a\)
\(a = 5 m/s^2\)
Correct Answer - `(M_(1))/(6), (M_(2))/(8), (M_(3))/(5)`
Given: F = 800 N, a = 5 m/s2, u = 0, t = 10 s To find: mass (m), distance travelled (s) Formulae: i. F = ma ii. s = ut + \(\frac{1}{2}\)at2 Calculation: From formula (i), ∴...
Correct option is:(D) 5 second \(F = \frac{dp}{dt}\) \(6 = \frac{mv}{dt}\) \(6 = \frac{1 \times 30}{dt}\) \(\Delta t = \frac{30}{6}\) \(\Delta t = 5 sec\)
Correct option is: (A) 0.6
B) Fnet , mass, acceleration
D) 120 cm/sec
Correct option is (B) 16 Kgs Average weight of 15 packets \(=\frac{5\times24+10\times12}{15}\) \(=\frac{120+120}{15}\) \(=\frac{240}{15}\) = 16 kg
